Question

a rectangular prism has a length of 5 cm, a width of 3 cm, and a height of 7 cm. what is the perimeter of the base of the prism?

Explanation:

Step1: Identify base shape

The base of a rectangular prism is a rectangle.

Step2: Recall perimeter formula

The perimeter formula for a rectangle is $P = 2(l + w)$, where $l$ is length and $w$ is width.

Step3: Substitute values

Given $l = 5$ cm and $w = 3$ cm, we have $P=2(5 + 3)$.

Step4: Calculate

$P = 2\times8=16$ cm.

Answer:

$16$ cm
