Question

The volume, V, of a box is a function of its height, h, in centimetres. If V(h) = 4h³ - 6h² + 80, what is the volume, in cubic ceintimetres when h = 3 cm?

Answer 1

Volume `V=134` cubic centimeters

Explanation:

Given `V(h)=4*h^3-6h^2+80`

at `h=3`,

`V(3)=4*3^3-6*3^2+80`

`V(3)=4*27-6*9+80`

`V(3)=108-54+80`

`V(3)=134`
