What is the volume of the square pyramid with base edges 54 yd and slant height 45 yd?

The answer is V = 34,992 y^3

You can answer this using an online calculator - calculator soup dot com under geometry then pyramid. Select given a (side length) and s (slant height). Enter the amounts to find V (volume).

To manually compute, get the h (height) first before computing for V (volume).

h^2 = l^2 - (s/2) ^2 : l (slant height), s (base edge/side)

h = √ ((45^2) - (54/2) ^2)

h = 36

Then find V (volume) : s (side), h (height)

V = 1/3 (s^2) (h)

V = 1/3 (54^2) (36)

V = 34,992 y^3
