Final answer:
The volume of a rectangular prism with dimensions 10 cm by 2 cm by 8 cm is found by multiplying the length by the width by the height, resulting in a volume of 160 cm³.
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply the length by the width by the height. The formula for the volume (V) is:
V = length × width × height
Given the dimensions of the rectangular prism are a length of 10 cm, a width of 2 cm, and a height of 8 cm, we would calculate the volume as follows:
V = 10 cm × 2 cm × 8 cm
V = 20 cm × 8 cm
V = 160 cm³
Therefore, the correct answer is (c) V = 160 cm³.
