Question 934741: You work for the BeeSwaks Candle Company and have been asked to update two of the company�s earliest candle designs, the Brick and the Egyptian. The original Brick was a cube 8 centimeters on a side. The original Egyptian was a pyramid 21 centimeters tall with a square base 10 centimeters on a side.

Improvements in the manufacturing process have made it possible to change the design of these candles for a fresh new look and improved profit. You have been asked to work within the following guidelines:

The Brick:
Shape- rectangular prism
Base- dimensions can vary, but it must be a square
Height- 1 cm less than the side length of the base

The Pyramid:
Shape- right square pyramid
Base- same dimensions as base of the Brick
Height- 21 cm

Question: Create a labeled diagram of the Brick. Use x to represent the length of a side of the base of the candle. Then write an equation for the volume of the candle in terms of x. Write the polynomial in standard form.

Volume of a pyramid= (1/3)Area of the base x Height

Drawing the picture easier done on paper than through sophisticated software and posting to an image hosting service.
The formulas for the volumes are easily done here.

BRICK VOLUME:
The two bottom dimensions are each x.
Volume is and necessary restriction is .
Standard form is probably but you might really want general form, .

PYRAMID VOLUME:
You already have the basic formula so this should be no trouble.
Volume is
simplifiable to
.
