Question

An empty box is shaped like a rectangular prism. The box has a base area of 9/10 square foot and a height of 1/3 foot. How much packing material is required to fill the box?
a. 3/10 ft^3
b. 1/10 ft^3
c. 1/3 ft^3
d. 2/3 ft^3

Answer 1

Since we already know the base area, we simply have to multiply it by the height to get the volume of the box (how much packing material it can contain)

9/10 x 1/3 

9     x     1   =  3
10          3       10       (I cancelled the 9 and 3 and made them 3 and 1                                                          respectively)
The answer is 3/10 ft³

Answer 2

The total amount of packing material required to fill the box is 3/10 cubic feet and this can be determined by using the formula of the volume.

Given :

• An empty box is shaped like a rectangular prism.
• The box has a base area of 9/10 square feet and a height of 1/3 feet.

The following steps can be used in order to determine the total amount of packing material required to fill the box:

Step 1 - The formula of the volume can be used in order to determine the total amount of packing material required to fill the box.

Step 2 - The formula of the volume of the box is given below:

$V = A \times H$

where A is the area of the box and H is the height of the box.

Step 3 - Now, substitute the values of A and H in the above expression.

$V = \dfrac{9}{10} \times \dfrac{1}{3}$

$V = \dfrac{3}{10}\;{\rm ft^3}$

Therefore, the correct option is a).
