Question

Find the volume of a 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

Base Area
= triangle base * triangle height /2
Prism volume
= Base Area * height

You have been given

triangle base: 7 ft
triangle height: 4 ft
prism height:8.5 ft

Apply the above formulas to calculate the volume required.

Answer 2

I don't know, I need someone to explain this.

Answer 3

85.5 ft^3 or cubed whatever you'd like to call it

Answer 4

WAIT I'M SORRY I forgot you were rounding it to the nearest whole number, in which case it would just be 86

Answer 5

this is a different question but its the same thing just with different numbers

triangle base = 5ft
triangle height = 3ft
prism height = 7.5ft

the answer choices
a. 56ft 3 (cubed)<-----that's my answer
b 19ft 3 (cubed)
c. 133ft 3 (cubed)
d. 8ft 3 (cubed)

what I did was multiply 5 x 3 and divide it my 2 cuz that's what you would do for a normal triangle and i got 7.5 so then i multiplied 7.5 by 7.5 and got 56.25 but it said to round to the nearest whole number so that would be 56ft cubed(a) is that right?
