Step-by-step explanation:
Set up an equation that shows the relation between the side length L of the cube and its surface S:
The side length of a cube with an area of 150 sq. ft is 5 ft. Now we can easily calculate the volume V:
The volume of a cube whose total surface area is 150 sq. ft. is 125 cubic feet.
Answer:
Perimeter of the figure = 198.54 feet
Step-by-step explanation:
Given figure comprises a rectangle and two semicircles.
Perimeters of two semicircle = 2πr
Here 'r' = Radius of the circle
Perimeter of two semicircles at the sides of the rectangle =
= 25π feet
= 78.54 feet
Length of side AB = Length of side CD = 60 feet
Perimeter of the given figure = 2(60) + 78.54
= 198.54 feet
