Answer: 96 Units^2
Step-by-step explanation:
Triangle Area: A = 1/2bh A=1/2(6)(2) Area=6
Rectangle Area(s): A=bh A= 6(7) = 42
A=bh A= 7(3) A= 21
Add them all up and you'd get
6+6+42+21+21 = 96
Since it's a cube all the side lengths are the same. So the calculation would be 6.1x6.1x6.1 or 6.1^3
V=226.981cm^3
V=Length x width x heigh

3200÷100=32
Since each model is 100, you need 32 to model 3,200
T=5
4=2+2/5t
Subtract 2 from both sides.
2=2/5t
Multiply both sides by 5/2.
t=5
