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

7 answers

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.
I don't know, I need someone to explain this.
85.5 ft^3 or cubed whatever you'd like to call it
WAIT I'M SORRY I forgot you were rounding it to the nearest whole number, in which case it would just be 86
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?
jyt
mine are

triangle base: 5 ft.
triangle height: 3 ft.
prism height: 7.5 ft

choices...
---------------
A. 56 ft^3
B. 19 ft^3
C. 113 ft^3
D. 8 ft^3
------------------
can you help please?
