b.

c.
225 mm2

d.
90 mm2

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.
