Question

A box shaped like a retangular prism has a volume of 280 in^3. Its dimensions are 4 in by (n+2) in by (n+5) in. Find n. How do I write the equation to solve this problem??

Answer 1

Multiply the 3 factors and solve. Remember length times width times height = Volume.

Answer 2

So 4(n+2)(n+5)?

Answer 3

Yes and that is equal to the volume which is given to be 280

Answer 4

Then divide both sides by 4.

Answer 5

Multiply the two binomials using FOIL then get it equal to 0, factor, and solve

Answer 6

Thank you :)
