Question

I am having trouble with this question. @hartnn
A cube is a solid ! gure with six square faces. If the edges of a cube have length 1.5 cm, what is the surface area of the cube? 
What is the relationship between the length of the edges and the area of each face? 
What is the relationship between the area of one face and the surface area of the whole cube?

Answer 1

Squares have edges that are all the same distance...
Any idea what the formula for area is? length * width. If the length and the width are the same (they are in squares) then its Length squared.
1.5^2 will give you the area of any given face.

There are 6 faces, and all of the faces have the same area. So the total surface area is the area you find above multiplied by 6.

Answer 2

Therefore my answer would be 13.5cm correct? @brookew41

Answer 3

can you see now the 6 square faces?

to find the Area of the whole figure, find the Area of each of the squarish faces and SUM them up

Answer 4

13.5 is the total surface area.... 2.25 per side/face of the cube.
