Question

What is the surface area of the rectangular prism?

125 m2

200 m2

250 m2

Answer 1

`\\$Surface area of a rectangular prism = The sum of the areas of the 6 rectangles formed by the height length and width.\\$S_A = 2(5^2 + 5\cdot 10 + 5\cdot 10) = 250m^2`

Answer 2

Surface area =250 m^2

Explanation:

Given the length of the prism is 10m

width is 5m and height is 5m

The formula for surface area =

2(length times width)+2(width times height)+2(height times length)

Plug in all the values in the formula

Surface area =
`2(10 \cdot 5) +2(5 \cdot 5)+2(5 \cdot 10)`

`=100+50+100=250`

Surface area =250 m^2
