Set kim's age to 2x. Set her sister's age to x. Now solve the equation:

2x+x=36
3x=36
x=12.

Remember, her sister's age was x, and x=12, so her sister is twelve. Kim's age is 12*2, so her age is 24.

V = (1/2) area of cross-section times length.

Note: I will use L in place of x to represent the length of the prism.

In short, V = (1/2)*b*h*L.

To find the surface area, use

A = bh + 2Ls + Lb

Volume given to be 15, 510.

Part (a) set up:

15, 510 = (1/2)(60)(11)L

Can you finish? Just solve for L to find your x-value.

Part (b) set up:

To answer part (b), you must find the value of L in part (a).

A = (60)(11) + 2L(61) + L(60)

Understand? Take it from here.
