Finding the volume/area

What is the area of this shape?

• 18cm
• 22cm²
• 18cm²
• 22cm

_{^{Which formula would I use of work out volume?
(NOTE: the measurements are in metres)}}

• 40m²
• 40m³
• 11m²
• Really should have listened more

What formula would I use to work out volume?

• l x w x h
• 1/2 (bxh)
• a + b + c
• l x w

What is the volume of the following shape? Equation: width*length*height

• 168
• 47
• 246
• 152

How do you find the surface area of a cube?

• LxWxH
• LxW
• LxWxHx6
• LxWx6

What is the surface area of a perfect cube that is 4 cm.

• 16 cm2
• 64 cm3
• 96 cm2
• math isn't hard, but I didn't listen

What is the ratio of surface area to volume  of a cube that is 2 cm.

• 6:1
• 2:1
• 6:5
• What is surface area again?

as the size of a cube grows-

• the surface area grows faster than the volume
• the volume grows faster than the surface area
• the surface area and volume grow at the same rate

Diffusion is the

• random distribution from low to high areas of concentration
• random distribution from areas of high concentration to low
• directed movement from areas of low to high concentration
• stealing from the rich and giving to the poor

• all areas receive it equally
• the center
• the outer edges
