Question

What is the surface area?
And an explanation too but if not it’s ok

Answer 1

The answer is 356 cm :)

Answer 2

356 cm.

Explanation:

Whenever you find the surface area of a rectangular prism, remember this mnemonic:

LISA WILSON LOST HER WITCH HAT TWICE.

(TWICE) 2 (LENGTH × WIDTH + LENGTH × HEIGHT + WIDTH × HEIGHT)

In this rectangular prism, the length is 8, the width is 14, and the height is 3 (the order of numbers in length, width, and height does not matter).

Now, we can just plug in the numbers.

LENGTH × WIDTH + LENGTH × HEIGHT + WIDTH × HEIGHT

`2(8*14+8*3+14*3) = 356.`

Therefore, the surface area of this rectangular prism is 356 centimeters.
