Question

Plz help ill give u brainlist

Answer 1

Area of the triangle base = 1/2 x 8 x 6 2/3 = 26 2/3 ft²

Volume = base area x height = 26 2/3 x 15 = 400 ft³

Volume = 400 ft³

Answer 2

Hey there :)

We know the volume formula of a triangular prism:
Volume = $\frac{(base)(height)}{2}$(of triangle) x height (of prism)

We are given the following:
Height of prism = 15 ft
Height of triangle = 8 ft
Base of triangle = $6\frac{2}{3}$ ft

Let us plug-in the given

V = $\frac{( 6\frac{2}{3})(8) }{2}$ x 15
   = $26 \frac{2}{3}$ x 15
   = 400 ft³
