A large cube is 2 feet on each edge. How many cubes - one inch on each edge- will it take to fill the large cube?
If the base of a triangle is increased by 20% and the altitude to that base is decreased by 40% then by what percent is the area changed?
Is that an increase or a decrease?
Decrease by 30%. Is this correct?
