Question

Sarah received a gift in a rectangular box with a volume of 240 in3. If the base of the box was 20 in2, how tall was the box?

Answer 1

V = l * w * h
240 = 20* h
divide both sides by 20
12 = h
height = 12 inches

Answer 2

Answer: 12 in.

Explanation:

We know that the volume of a rectangular prism is given by :-

`\text{Volume}=\text{Base area}* \text{height}`

Since, the volume of the rectangular box =
`240\ in^3`

The base area of the box =
`20\ in^2`

Let h be the height of the box.

Substitute these values in the above formula , we get

`\text{240}=20* h\\\\\Rightarrow\ h=(240)/(20)=12\ in.`

Hence, the height of the box = 12 in.
