## Surface area of a Pyramid 57 yards by 69 foot by 70 inches

Steps:

The Surface area of Pyramid A = $lw+l$$\sqrt{(\frac{w}{2})^2+(h)^2}$$+w$$\sqrt{(\frac{l}{2})^2+(h)^2} Substitute the values of the length l = 57 yd, the width w = 69 ft and the height h = 70 in into the formula for surface area of a pyramid Unit Conversion of 70 in = 1.9444444 yd To convert Inche to Yards we know that, 1 Inche = 0.02778 Yards or 1 Inche = 1/36 Yards To convert Inche to Yards, divide the inche value by 36 Result in Foot: 70 × in/12 × yd/in Cancel The Comman factor of in Result in Foot: 70/36 Divide the 70 by 36 Result in Yards: 1.9444444 yards ∴ 70 Inche = 1.9444444 yards Unit Conversion of 69 ft = 23.0 yd To convert Feet to Yards we know that, 1 Foot = 0.333333 or 1 Foot = 1/3 Yards To convert Feet to Yards, divide the feet value by 3 Result in Yards: 69 × ft/yd × ft/yd Cancel The Comman factor of ft Result in Yards: 69/3 yd Divide the 69 by 3 Result in Yards: 23.0 yards ∴ 69 Feet = 23.0 yards A=(57 \cdot23.0+57$$\sqrt{(\frac{23.0}{2})^2+(1.9444444)^2}$$+23.0$$\sqrt{(\frac{57}{2})^2+(1.9444444)^2}$) yd

Simplify each term.

Multiply 57 yd by 23.0 yd

A = $1311.0+57$$\sqrt{(\frac{23.0}{2})^2+(1.9444444)^2}$$+23.0$$\sqrt{(\frac{57}{2})^2+(1.9444444)^2} Square root of \sqrt{(\frac{23.0}{2})^2+(1.9444444)^2} is 11.663227 Put The values in Area Formula: A= 1311.0+ 57 \cdot 11.663227+23.0$$\sqrt{(\frac{57}{2})^2+(1.9444444)^2}$

Square Root of $\sqrt{(\frac{57}{2})^2+(1.9444444)^2}$ is 4.2462765

Put The values in Area Formula:

A= 1311.0 + (57 x 11.663227) + (23.0 x 4.2462765)

Multiply 57 and 11.663227

A= 1311.0 + 664.8039389 + (23.0 x 4.2462765)

Multiply 23.0 and 4.2462765

A= 1311.0 + 664.8039389 + 97.6643593

A= 1975.8039389 + 97.6643593

A= 2073.4682982 yd2

∴ The Surface Area of Pyramid length 57 yd , width 69 ft and height 70 in is 2073.4682982 yd2

or

Unit Conversion of 69 ft = 828.0 in

To convert Foot to Inches

we know that, 1 Foot = 12 inches

To convert Foot to inches, multiply the foot value by 12.

Result in Foot: 69 ft × 12 × in/ft

Cancel The Comman factor of ft

Result in Inches: (69 x 12 in)

Multiply 69 into 12

Result in Inches: 828.0 inches

∴ 69 Foot = 828.0 inches

Unit Conversion of 57 yd = 2052.0 in

To convert Yard to Inches

we know that, 1 Yard = 36 inches

To convert Yard to inches, multiply the yard value by 36.

Result in Yards: 57 yd x 36 × in/yd

Cancel The Comman factor of yd

Result in Inches: (57 x 36 in)

Multiply 57 into 36

Result in Inches: 2052.0 inches

∴ 57 Yards = 2052.0 inches
