a house has a roof in a form of square pyramid with base of 8m and slant height of 3 m. what is the volume of the roof ?


Sagot :

Answer:

SQUARE PYRAMID

Given

Base (b) = 9 m

Slant height (s) = 4.5 m

Surface Area (S) = ?

Calculate the perimeter of the base.

P = 4b

P = (4)(9)

P = 36 m

Calculate the area of the base

A = b²

A = (9)²

A = 81 m²

Calculate the surface area of the square pyramid.

S = A + 1/2Ps

S = 81 + (1/2)(36)(4.5)

S = 81 + 81

S = 162 m²
