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.

Step-by-step explanation:

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

$\text{Volume}=\text{Base area}\times \text{height}$

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

$\text{240}=20\times h\\\\\Rightarrow\ h=\frac{240}{20}=12\ in.$

Hence, the height of the box = 12 in.
