Answer 1

Hey there! Welcome to QuestionCove!

Do you know the formula for surface area?

Do you know what surface area is? It's just adding up the area of every single surface of our rectangular prism. But there's formulas to make it a little less work

Answer 2

Surface Area = 2(LW + WH + LH)

Where L is length, W is width, and H is height

Don't forget, each cube has a side of 7 m so for example, the width has two cubes so that length is actually 14 m. Not 2 m. It's going to be 14 m. So similarly first find what the height and length are and then plug in those values into the formula I just shared.
