Question

The volume of this prism is 4950cm3.
The area of the cross-section is 110cm2.
Work out x

Answer 1

45cm

Explanation:

length × cross section = volume

in this case we call the unknown
`x`

so

`x` x 110 = 4950

to get
`x` you divide the volume by the cross section

`(4950)/(110)`=
`x`

so
`x` = 45cm
