3. The area of the base of a can is 45 square inches. Its height is 12 inches. If 1/3 of the

height is cut off, what will be the volume of the can?*

a) 540 cubic inches

b)180 cubic inches

c) 280 cubic inches

d) 360 cubic inches

Answer 1

The correct answers is D

D) 360 cubic inches

Explanation:

We know that the Area of the base of the can is given by

A = 45 inch²

Initial height of the can = 12 inches

Fraction of height cut off = 1/3

Calculate the final height after cutting off:

Find 1/3 of 12 inches:

`(1)/(3)\cdot12=4`

Subtract the answer from 12 to get final height:

Final height = 12- 4 = 8 inches

Can is a form of cylinder, so:

Volume = (Area)(height)

`V=45\cdot8\\V=360inch^3`
