Cheng likes a modern lawn sculpture made of four identical solid right pyramids with square bases. He decides to create an exact

lara [203]

Answer:

d. $8\text{ ft}^3$

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:

$\frac{6\text{ ft}}{4}=1.5\text{ ft}$

We know that volume of a pyramid is equal to 1/3 of base area times height that is $V=\frac{bh}{3}$ , where b represents area of base.

$V=\frac{(2\text{ ft})^2\times\text{ 1.5 ft}}{3}=4\times 0.5\text{ ft}^3=2\text{ ft}^3$

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.
