Question

A pyramid has a square base that is 160 m on each side. What is the perimeter of the base in kilometers?

Answer 1

Explanation:

The answer should be 640,000 bc you are adding the square base. Squares are 4 sides so 4x 160=640. Kilometers are 1,000, so you multiply 640x1,000 to get your answer.

Answer 2

A pyramid has a square base. The perimeter of the base in kilometers is 0.640 kilometers.

Solution:

Given that pyramid has a square base

Each side of the base = 160 m

Need to determine perimeter of base in kilometer.

Perimeter of Square = 4 x length of side of square

Perimeter of square base having side as 160 meters = 4 x 160 = 640 meters

We need answer in kilometers

As 1000 meters = 1 kilometer

`\begin{array}{l}{\Rightarrow 1 \text { meter }=(1)/(1000) \text { kilometers }} \\\\ {\Rightarrow 640 \text { meter }=640 \mathrm{x} (1)/(1000) \mathrm{kilometers}} \\\\ {\Rightarrow 640 \mathrm{meter}=0.640 \mathrm{kilometers}}\end{array}`

Hence perimeter of square base of pyramid having base side as 160 meters is 0.640 kilometers
