Paperweight Cobalt

help with pre-calculus?

At a glassware factory, molten cobalt glass is poured into molds to make paperweights. Each mold is a rectangular prism whose height is 3 inches greater than the length of each side of the square base. A machine pours 20 cubic inches of liquid glass into each mold. What are the dimensions of the mold?
any help with this one is appreciated

An aspirin tablet in the shape of a right circular cylinder had height centimeter and radius centimeter. The manufacturer also wishes to market the aspirin in capsule form. The capsule is to be centimeters long, in the shape of a right circular cylinder with hemispheres attached at both ends. Find the radius of the capsule so that its volume is equal to that of the tablet.
any help with this one is good too!!!!
the table has a height of 1/3 cm and a radius of 1/2cm. the capsule is 3/2 cm long
the tablet has a height of 1/3cm and a radius of 1/2cm. The capsule is 3/2 cm long

First one, x²(x+3) = 20, so solve x^3 + 3x² - 20 = 0, and get x=2, so mould is 2x2x5.

Second one, tablet volume is πr²h = (1/2)²(1/3)π = π/12 cc. Capsule is cylinder + sphere, πr²(3/2 - 2r) + (4/3)πr^3, so

(4/3)πr^3 - 2πr^3 + (3/2)πr² = π/12
(-2/3)πr^3 + (3/2)πr² = π/12
-8r^3 + 18r² = 1
8r^3 - 18r² + 1 = 0
r = -.2247 .... useless solution, neg. radius
r = 2.2247 .... useless solution, (3/2-2r) gives negative volume
r = 0.25 cm
