Question

A small rectangular tissue box is 0.5ft long, 0.2ft wide and 0.3 ft deep. The box is completely filled with tissues1. what is the area of the top of the tissue box?2. How many cubic feet of tissues will the box hold?3. Express your answers to the previous two questions as powers of 10.

Answer 1

Given:

Length = 0.5 ft.

Width = 0.2 ft.

Height = 0.3 ft.

1.) Area of the top of the tissue box.

`\text{ Area = Length x Width}`
`\text{ = 0.5 x 0.2}`
`\text{ Area = 0.2 sq. ft.}`

2.) Cubic feet of tissues will the box hold.

`\text{ Volume = Length x Width x Height}`
`\text{ = 0.5 x 0.2 x 0.3}`
`\text{ Volume = 0.03 cu. ft.}`

3.) Expressing the answer as powers of 10.

`\text{ Area = 0.2 sq. ft. = 2 x 10}^(-1)\text{ sq. ft.}`
`\text{ Volume = 0.03 cu. ft. = 3 x 10}^(-2)\text{ cu. ft.}`
