Answer:
The volume is: 127.5 inches ^3
Step-by-step explanation:
Formula of "volume of a triangle":
length * width * height /2
* = multiply
/ = divide
That means we need to do:
5 * 6 * 8.5 = 255 in
then divide it by 2
255/2
127.5 in ^3
^ = exponent
The volume is: 127.5 inches ^3
Hope this helped :)
