STEP 1: Calculate the perimeter of the tabletop. Since the tabletop has the shape of a square, use the formula for the perimeter of a square.

Perimeter = 4 × S

Perimeter = 4 × 48"

Perimeter = 192"

STEP 2: Convert inches to feet (see conversion table in appendix).

192" × .08333 = 16'

CHAPTER EIGHT

Solid Figure Formulas

From chapter six, you know that a solid figure has three dimensions: length, width and depth. Two important measurements of a solid figure are volume and surface area. Volume is a measure of the three-dimensional size of a solid figure. Surface area, you will recall from chapter seven, is a measure of the amount of surface on the figure. This chapter provides formulas for calculating the volume and surface area for several of the solid figures shown in chapter six. Volume is measured in cubic units (cubic inches, cubic feet, cubic millimeters, cubic meters, etc.). Surface area is measured in square units (square inches, square feet, square millimeters, square meters, etc.).
