Question

What is the surface area of a die in which each edge has a length of 15 millimeters? (Hint: On a cube, the length, width, and height have the same measure.)





1,350 mm2

450 mm2

180 mm2

1,687.5 mm2

Answer 1

What is the area of one face of the cube?

Answer 2

15mm

Answer 3

that's one side, not the area

Answer 4

Area of one face = ???

Answer 5

So you would times 15 by 2?

Answer 6

Area = base * height

A = b*h

A = 15*15

A = 225

Answer 7

There are 6 of these faces in a cube (look at any dice)

so total surface area is 225*6 = 1350 sq mm
