Question

Please help! Especially with the steps!

Answer 1

A) the base is a square to find its area you can use the formula:
$a = {s}^{2}$
a being the area and s one of the sides

now just use s= 55ft
$a = {55}^{2} = 3025$
The area of the base is 3025 ft^2

b) the volume of the pyramid is:
$v = \frac{b \times h}{3}$
v being the volume, b the area of the base and h the height of the pyramid
use b=3025 and h=460
$v = \frac{3025\times 460}{3} = 463833.3$
the volume of the pyramid is 463833.3 ft^3
