Designing a Solar Oven A science class has been assigned the task of developing a simple solar oven using a cardboard box as the base. The solar oven should be able to melt cheese for nachos, and the temperature should reach at least
140 °F. The total cost of the materials used must be less than $10 and the size of the oven must be 24” x 24” or less. The required temperature must be met within 60 minutes. The final outcome of the class project should be that the oven uses solar energy to make a plate of nachos, reaching the minimum temperature in the required amount of time.

The class used this design for its solar oven.

Which statements describe constraints that the science class’s solar oven must meet? Choose all of the correct responses.

A. It should use a box of some type.

B. It should be able to melt the cheese on the chips.

C. It must reach the given temperature within one hour.

D. The total cost of materials should be $10 or less.

E. It can be used by people in remote areas without access to electricity
