You find the area of one side of the cube which is 12.25 mm and multiply it by the number of side which is 6. and the answer is 73.5 mm
The answer is 5 I just took the test
You were supposed to find the area of the darkened area
16x2=32
21x2=42
32+42=54
the perimeter is 54
It shows the Ora scale for area multiply width and length
The answer would be 720 because you times all sides length times width times height
