Question

Can someone please help me with this (we are finding the volume)

Answer 1

To find,

the Volume of the prism.

we know that,

Volume of the prism is product of the area of the base and the height of the prism.

Area of the base:

From the given prism, the base is triangle.

Base length (b)=72 cm

Height (h)=45 cm

Area of the triangle=

`(1)/(2)* b* h`
`=(1)/(2)*72*45`
`=36*45`
`=1620cm^2`

Height of the prism is 80 cm,

we get,

Volume of the prism is,

`=1620*80`
`=129600cm^3`

Answer is:129600 cm cube.
