Question

Here is a picture of a cube and the net for this cube.

Answer 1

Answer:

Option (A) 1,350 mm² is the answer.

Step-by-step explanation:

In this question we have been given a picture of cube and net for this cube.

We have to find the surface area of the cube.

Surface area of cube = surface area of net

               = 6 (surface area of one square) × (number of squares)

                = 6 (15)² ⇒ (since one side of square = 15 mm )

                = 6 (225)

                = 1350 mm²

Option (A) 1,350 mm² is the answer.

Answer 2

The answer is A. 1350 because a cube has 6 squares and each side length of the square is 15 and the area of one square is 15 x 15 = 225 and as said, there's 6 squares so multiply 225 x 6 = 1350. Hope this helped! :)
