l - length

w - width

h - height

We have:

l=7x^3,\ w=5x^2,\ h=2x^4

Substitute:

V=(7x^3)(5x^2)(2x^4)=(7\cdot5\cdot2)(x^3x^2x^4)=70x^{3+2+4}=70x^9

Used

a^n\cdot a^m=a^{n+m}

Would you rather have pennies to match your weight or quarters to match your height
mezya [45]

Answer:

First you have to divide the number by the weight of one penny (which is 2.5 grams) then take what you get and multiply by the value of one penny (and that is $0.01).
