Question

Find the slant height of the pyramid. Approximate to one decimal place as needed.

30 in
8 in
30 in

Answer 1

17 inches

Explanation:

The given shape is square pyramid.

Given,

Height (H) = 8 in

Base side's length (s) = 30 in

To find : Slant height (l)

Formula

l² = H² + (s/2)²

l² = 8² + (30/2)²

l² = (8 x 8) + 15²

l² = 64 + (15 x 15)

l² = 64 + 225

l² = 289

l² = 17 x 17

l² = 17²

l = 17 in
