Answer:
area: 64
perimeter: 32
Step-by-step explanation:
8*8=64
8+8+8+8=32
Start with the original equation.
Subtract 
from both sides.
Divide both sides by 
.
Vol=area x Height
length= 3
breadth= X
Height = 2
area must = half of 42 because to get the volume of 42cm cubed, you had to times the area by 2 so
42 devided by 2 is 21 so to find the length you myst do 21 devided by 3 which is 7
so the missing length is 7cm
