Question

Find the volume of triangular prism with the following dimensions. Round to the nearest whole number.

Triangle base= 7 ft.
triangle height= 4 ft
prism height: 8.5 ft

Answer 1

124.0 ft^2

Explanation:

let b = base of triangle = 7ft

h = height of triangle = 4ft

and

l = height of prism. = 8.5ft

We know,

volume of prism = area of triangular face of prizm × height of prizm

= 1/2 × b × h × l

= 1/2 × 7 × 4 × 8.5

= 7 × 2 × 8.5

= 14 × 8.5

= 124.0 ft^2
