Given:
Length = 0.5 ft.
Width = 0.2 ft.
Height = 0.3 ft.
1.) Area of the top of the tissue box.
[tex]\text{ Area = Length x Width}[/tex][tex]\text{ = 0.5 x 0.2}[/tex][tex]\text{ Area = 0.2 sq. ft.}[/tex]
2.) Cubic feet of tissues will the box hold.
[tex]\text{ Volume = Length x Width x Height}[/tex][tex]\text{ = 0.5 x 0.2 x 0.3}[/tex][tex]\text{ Volume = 0.03 cu. ft.}[/tex]
3.) Expressing the answer as powers of 10.
[tex]\text{ Area = 0.2 sq. ft. = 2 x 10}^{-1}\text{ sq. ft.}[/tex][tex]\text{ Volume = 0.03 cu. ft. = 3 x 10}^{-2}\text{ cu. ft.}[/tex]
