You plan to construct a brick wall measuring 14.5 ft. in length, 5.5 ft. high, and 0.5 ft. in width. If a brick measures 6 in. x 4 in. x 2 in. you will need 3,240 bricks.
What is the volume of the cuboid?
The volume of the cuboid is the product of the length, breadth, and height of the given prism.
Volume of cuboid = (length x width x height)
We have given that
Dimensions of a brick wall is given by
Length = 14.5 feet
Width = 0.5 feet
Height = 5.5 feet
Dimensions of a brick is given by
Length = 6 inch
Width = 4 inch
Height = 2 inch
First of all, we will convert the dimensions of a wall from feet into inches.
1 feet = 12 inch
15 feet = 12*15 inch = 180 inch
6 feet = 12*6 inch = 72 inch
We know that volume of a brick wall will be equal to the volume of 'n' bricks, so we can set an equation;
The volume of a brick wall = the volume of 'n' bricks
180 x 72 x 12 = n x 6 x 4 x 2
155520 = n x 48
n = 3240
Therefore, you will need 3,240 bricks.
