Question

Mary has 6 identical boxes. The rectangular base of each box has an area 1 1/3 ft ^3. The height of each box is 10 inches. What is the total volume of all the boxes in cubic feet?

Express the answer in mixed fractions.

Answer 1

Volume = area of the base × height

V= L× w × h =B × h

the volume for one box = 1 1/3 × 10

= 40/3 = 13 1/3

the volume for 7 boxes= 6 × 13 1/3 = 80 ft^3

Note : Area has square unit
