Steps:
The Surface area of Pyramid A = $lw+l$$\sqrt{(\frac{w}{2})^2+(h)^2}$$+w$$\sqrt{(\frac{l}{2})^2+(h)^2}$
Substitute the values of the length l =5 cm, the width w =7 in and the height h =7 in into the formula for surface area of a pyramid Unit Conversion of 5 cm = 1.9685039 in
5 Centimeters is 1.9685039 inches
To convert Centimeter to Inches
we know that, 1 Centimeter = 0.393705 inches or
1 Centimeter = 1/2.54 inches
To convert Centimeters to inches, divide the centimeter value by 2.54.
Result in Centimeters: 5 × cm/2.54 × in/cm
Cancel The Comman factor of cm
Result in Inches: 5/2.54 in
Divide the 5 by 2.54
Result in Inches: 1.9685039 inches
∴ 5 Centimeters = 1.9685039 inches
A=($1.9685039 \cdot7+1.9685039$$\sqrt{(\frac{7}{2})^2+(7)^2}$$+7$$\sqrt{(\frac{1.9685039}{2})^2+(7)^2}$) in
Simplify each term.
Multiply 1.9685039 in by 7 in
A = $35.0+1.9685039$$\sqrt{(\frac{7}{2})^2+(7)^2}$$+7$$\sqrt{(\frac{1.9685039}{2})^2+(7)^2}$
Square root of $\sqrt{(\frac{7}{2})^2+(7)^2}$ is 7.8262379
Put The values in Area Formula:
A= $35.0+ 1.9685039 \cdot 7.8262379+7$$\sqrt{(\frac{1.9685039}{2})^2+(7)^2}$
Square Root of $\sqrt{(\frac{1.9685039}{2})^2+(7)^2}$ is 7.0688579
Put The values in Area Formula:
A= 35.0 + (1.9685039 x 7.8262379) + (7 x 7.0688579)
Multiply 1.9685039 and 7.8262379
A= 35.0 + 15.4059799 + (7 x 7.0688579)
Multiply 7 and 7.0688579
A= 35.0+ 15.4059799 + 49.4820052
Add 35.0 and 15.4059799
A= 50.4059799 + 49.4820052
A= 99.8879851 in2
∴ The Surface Area of Pyramid length 5.0 cm , width 7 in and height 7 in is 99.8879851 in2
or
Unit Conversion of 7 in = 17.78 cm
7 Inches is 17.78 Centimeters
To convert Inches to Centimeters
we know that, 1 Inche = 2.54 Centimeters
To convert Inches to Centimeters, multiply the inche value by 2.54
Result in Centimeters: 7 in × 2.54 × cm/in
Cancel The Comman factor of in
Result in Centimeters: (7 x 2.54 cm)
Multiply 7 into 2.54
Result in Centimeters: 17.78 Centimeters
∴ 7 Inches = 17.78 Centimeters
Unit Conversion of 7 in = 17.78 cm
7 Inches is 17.78 Centimeters
To convert Inches to Centimeters
we know that, 1 Inche = 2.54 Centimeters
To convert Inches to Centimeters, multiply the inche value by 2.54
Result in Centimeters: 7 in × 2.54 × cm/in
Cancel The Comman factor of in
Result in Centimeters: (7 x 2.54 cm)
Multiply 7 into 2.54
Result in Centimeters: 17.78 Centimeters
∴ 7 Inches = 17.78 Centimeters
A=($5.0 \cdot17.78+5.0$$\sqrt{(\frac{17.78}{2})^2+(17.78)^2}$$+17.78$$\sqrt{(\frac{5.0}{2})^2+(17.78)^2}$) cm
Simplify each term.
Multiply 5.0 cm by 17.78 cm
A = $88.9+5.0$$\sqrt{(\frac{17.78}{2})^2+(17.78)^2}$$+17.78$$\sqrt{(\frac{5.0}{2})^2+(17.78)^2}$
Square root of $\sqrt{(\frac{17.78}{2})^2+(17.78)^2}$ is 19.8786443
Put The values in Area Formula:
A= $88.9+ 5.0 \cdot 19.8786443+17.78$$\sqrt{(\frac{5.0}{2})^2+(17.78)^2}$
Square Root of $\sqrt{(\frac{5.0}{2})^2+(17.78)^2}$ is 17.9548991
Put The values in Area Formula:
A= 88.9 + (5.0 x 19.8786443) + (17.78 x 17.9548991)
Multiply 5.0 and 19.8786443
A= 88.9 + 99.3932216 + (17.78 x 17.9548991)
Multiply 17.78 and 17.9548991
A= 88.9 + 99.3932216 + 319.2381052
Add 88.9 and 99.3932216
A= 408.1381052 + 319.2381052
A= A= 727.3762103 cm2
∴ The Surface Area of Pyramid length 5 cm , width 7 in and height 7 in is 727.3762103 cm2
