Answer 1

C because you have to multiply the four measures together.

Answer 2

Answer: C. 128 cu. ft.

Explanation:

We know that the volume of a rectangular prism is given by :-

`V=\text{Length*width*height}`

Given : The dimensions of the cord of wood is a bundle : 4 feet by 4 feet by 8 feet.

Then , the volume of a cord of wood will be :-

`\text{Volume}=4*4*8\\\\\Rightarrow\text{Volume}=128\text{ cubic feet}`

Hence, the volume of a cord of wood = 128 cu. ft.
