The volume of a rectangular box= 1056 ft³
The surface area of a rectangular box= 632 square ft
What is meant by volume?
Volume is a measure of three-dimensional space that is occupied. It is frequently quantified numerically using SI-derived units or different imperial or US customary units (such as the gallon, quart, cubic inch). The definition of length (cubed) is related to volume. The volume of a container is commonly believed to be its capacity; that is, the amount of fluid (gas or liquid) that the container can hold, rather than the amount of space it occupies.
Volume was measured in ancient times using similar-shaped natural containers, and later, standardized vessels. Arithmetic formulas can quickly compute the volume of some simple three-dimensional shapes.
Given,
Length of the rectangular box= 11ft
Width of the rectangular box= 8 ft
Height of the rectangular box= 12 ft
Volume= Length× Width× Height
Volume= 11×8×12
=1056 ft³
Therefore, volume= 1056ft³
Surface area of a rectangular box is,
1 and 2 surfaces, 11 × 8 ===>
Surface area = 2× (11× 8) = 176 square ft
1 and 3 surfaces 11 × 12 ===>
Surface area = 2× (11×12) = 264 square inches
3• 2 surfaces 12 × 8 ===>
Surface area = 2× ( 12 × 8) = 192 square inches
Adding all the surface areas
176 +264 +192= 632 square ft.
The surface area of a rectangular box= 632 square ft
