Question

Find the volume of the prizm to the nearest 10th
(6th-grade math)

Answer 1

1) 178.2
`in^(3)`

Explanation:

The formula for the area of a triangle is :
`(base* height)/(2)`

To work this out you would first need to find the area of the triangle. You can do this by first multiplying the base of 4.5 by the height of 2.2, which gives you 9.9. Then you would divide 9.9 by 2, which gives you 4.95. You would do this because the formula to work out the area of a triangle is the same as that of a square, however a triangle is half of a square with the same dimensions. To work out the volume you would multiply the area of 4.95 by the length of 36, which gives you 178.2 inches cubed.

1) Multiply 4.5 by 2.2.

`4.5*2.2=9.9`

2) Divide 9.9 by 2.

`9.9/2=4.95`

3) Multiply 4.95 by 36.

`4.95*36=178.2 inches^(3)`
