Answer:
d.
Step-by-step explanation:
We have been given that Cheng measures each edge of each base to be 2 feet. The height of the whole sculpture is 6 feet.
First of all, we will find height of each pyramid by dividing height of whole sculpture by 4 as:
We know that volume of a pyramid is equal to 1/3 of base area times height that is , where b represents area of base.
Since volume of one pyramid is equal to 2 cubic feet, so volume of 4 pyramids will be 4 times 2 cubic feet that is 8 cubic feet.
Therefore, Cheng must purchase 8 cubic feet of material.

Answer:
7,425 gallons of water
Step-by-step explanation:
Given:
A tank of,
Length = 16.5 ft
Width = 7.5 ft
Height = 8 ft
1 ft³ = 7.5 gallons of water
Required:
Gallons of water that will fill the tank
SOLUTION:
Find the volume of the tank:
Volume of the tank = length*width*height
Volume = 16.5*7.5*8 = 990 ft³
Convert 990 ft³ to gallons of water:
1 ft³ = 7.5 gallons
990 ft³ =
= 7,425 gallons of water
7,425 gallons of water will fill the tank of the given measurement.
