A rectangle box measures 6.00 in. in length, 7.00 in. in width, and 8.00 in. in height. The volume of the rectangular box is 5.506 L
Given,
1 inch = 2.54 cm
Length = 6.00 inches = 6.00 x 2.54 cm = 15.24 cm
Width = 7.00 inches = 7.00 x 2.54 cm = 17.78 cm
Height = 8.00 inches = 8.00 x 2.54 cm = 20.32 cm
Now,
Volume of rectangular box = Length x Width x Height
= 15.24 cm x 17.78 cm x 20.32 cm
= 5506.05 cm3
= 5506.05 mL (\small \because 1 cm3 = 1 mL)
= 5.506 L (\small \because 1000 mL = 1 L)
Hence, the volume of rectangular box is 5.506 L.
