Answer:
Step-by-step explanation:
According to the problem, the baker needs square prism molds with 30 centimeters side and 6 centimeters depth (or height).
If the molds are square prisms, that means the bottom or base is square with 30 centimeters each side. The area of the bottom is
[tex]A=l^{2}[/tex], where [tex]l=30[/tex], replacing values, we have
[tex]A=30^{2}=900cm^{2}[/tex]
Therefore, the baker is going to need 900 square centimeters of paper for each mold.
