Question

Please help me with this:)

Answer 1

55.4 in³

Explanation:

The volume (V) of a triangular prism is

V = area of triangular face × length

note the triangle is equilateral with area (A)

A =
`(s^2√(3) )/(4)` ( s is the length of the side )

=
`(16√(3) )/(4)` = 4
`√(3)` in², hence

V = 4
`√(3)` × 8 = 32
`√(3)` ≈ 55.4 in³
