What is the volume of the triangular prism to the nearest whole unit?

Question

Height = 3 ft
Width = 15 ft
Length = 16 ft

A. 360 ft
B. 240 ft
C. 1,440 ft
D. 720 ft

I need help ASAP

Answer 1

the area of the base times the height
if the base is an equilateral triangle with base 15 and altitude 16, then
A = (1/2)(15)(16) = 15 * 8 = 120 ft^2
and Volume = 120 * 3 = 360 ft^3
HOWEVER, I do not know what your triangular base looks like from your description

Answer 2

Since you have only 2 dimensions given for the triangular base,
I must conclude that the triangle is right-angled
So volume = (1/2)(15)(16)(3) cubic ft
= ...

All your answer choices should be ft^3
