Question

If x = 7 units, y = 15 units, and z = 6 units, then what is the surface area
630 right?

Answer 1

Surface area of a cuboid is basically the area of all faces.
So you would have 2xz+2xy+2yz. that gives a total of 6 faces.
Does that help, or do you just want to confirm that your answer is right?

Answer 2

your answer would then be 474

Answer 3

well 2 × 42 units2 + 2 × 90 units2 + 2 × 105 units2
= 474 units2
