## Surface area of a Pyramid 3 yards by 40 foot by 7 meters

Steps:

The Surface area of Pyramid A = $lw+l$$\sqrt{(\frac{w}{2})^2+(h)^2}$$+w$$\sqrt{(\frac{l}{2})^2+(h)^2} Substitute the values of the length l = 3 yd, the width w = 40 ft and the height h = 7 m into the formula for surface area of a pyramid Unit Conversion of 7 m = 7.6552973 yd To convert Meter to Yards we know that, 1 Meter = 1.0936139 Yards To convert Meter to Yards, multiply the mile value by 1.0936139 Result in Yards: 7 m × 1.0936139 × yd/m Cancel The Comman factor of m Result in Yards: (7 x 1.0936139 yd) Multiply 7 into 1.0936139 Result in Yards: 7.6552973 yards ∴ 7 Meter = 7.6552973 yards Unit Conversion of 40 ft = 13.3333333 yd To convert Feet to Yards we know that, 1 Foot = 0.333333 or 1 Foot = 1/3 Yards To convert Feet to Yards, divide the feet value by 3 Result in Yards: 40 × ft/yd × ft/yd Cancel The Comman factor of ft Result in Yards: 40/3 yd Divide the 40 by 3 Result in Yards: 13.3333333 yards ∴ 40 Feet = 13.3333333 yards A=(3 \cdot13.3333333+3$$\sqrt{(\frac{13.3333333}{2})^2+(7.6552973)^2}$$+13.3333333$$\sqrt{(\frac{3}{2})^2+(7.6552973)^2}$) yd

Simplify each term.

Multiply 3 yd by 13.3333333 yd

A = $39.9999999+3$$\sqrt{(\frac{13.3333333}{2})^2+(7.6552973)^2}$$+13.3333333$$\sqrt{(\frac{3}{2})^2+(7.6552973)^2} Square root of \sqrt{(\frac{13.3333333}{2})^2+(7.6552973)^2} is 10.1512571 Put The values in Area Formula: A= 39.9999999+ 3 \cdot 10.1512571+13.3333333$$\sqrt{(\frac{3}{2})^2+(7.6552973)^2}$

Square Root of $\sqrt{(\frac{3}{2})^2+(7.6552973)^2}$ is 7.7041273

Put The values in Area Formula:

A= 39.9999999 + (3 x 10.1512571) + (13.3333333 x 7.7041273)

Multiply 3 and 10.1512571

A= 39.9999999 + 30.4537713 + (13.3333333 x 7.7041273)

Multiply 13.3333333 and 7.7041273

A= 39.9999999 + 30.4537713 + 102.7216965

A= 70.4537712 + 102.7216965

A= 173.1754677 yd2

∴ The Surface Area of Pyramid length 3 yd , width 40 ft and height 7 m is 173.1754677 yd2

Unit Conversion of 40 ft = 12.192 m

To convert Feet to Meter

we know that, 1 Foot = 0.3048 Meter

To convert Foot to meters, multiply the feet value by 0.3048.

Result in Meter: 40 ft × 0.3048 × m/ft

Cancel The Comman factor of ft

Result in Meters: (40 x 0.3048 m)

Multiply 40 into 0.3048

Result in Meters: 12.192 meters

∴ 40 Foot = 12.192 meters

Unit Conversion of 3 yd = 2.7432 m

To convert Yard to Meter

we know that, 1 Yard = 0.9144 Meter

To convert Yards to meters, multiply the yard value by 0.9144.

Result in Meter: 3 yd × 0.9144 × m/yd

Cancel The Comman factor of yd

Result in Meters: (3 x 0.9144 m)

Multiply 3 into 0.9144

Result in Meters: 2.7432 meters

∴ 3 Yard = 2.7432 meters
