1) A model of a storage compartment is to a scale of 1:40. If the surface area of the model is 25 square centimeters, what is the surface area of the actual storage compartment?

a) The storage compartment in the last question has an actual volume of 8 cubic metres. What is the volume of the model?



If the door on the model of the storage shed is 2 cm wide and 4 cm high then its area is 2 x 4 = 8 sq cm. The door on the actual storage shed is then 80 cm wide and 160 cm high giving an area of 80 x 160 = 12800 sq cm.

Does this help?
