1. Warm-Up #1 11/30 1. Write down these 3 formulas:
Surface area (cm2) = length x height x 6 (sides)
Volume (cm3) = length x width x height
Surface Area to volume ratio (cm) = surface area
volume
2. Calculate the surface area and volume of the cube:
Warm-Up # /30
Length = 3cm
Width = 3cm
Height = 4cm

2. Answer
Surface area = 3x3x6=54
Volume = 3x3x4 = 36

3. Warm-Up # /1
1. Calculate the surface area and volume of the cubes with the following measurements: CUBE A CUBE B length = .5cm length = 1cm width = 1cm width = .5cm height = 1cm height = .5cm 2. Calculate the surface area to volume ratio for each cube. Which cube has a greater surface area to volume ratio?

4. Answers Cube A: surface area = .5 x1 x 6 = 3 volume = .5 x 1 x 1 = .5
ratio = 3/.5 = 6
Cube B: surface area = 1 x .5 x 6 = 3
volume = 1 x .5 x .5 = .25
ratio = 3/.25 = 12
Cube B has a greater surface area to volume ratio
