Jordan purchased a piece of fabric that is 16 cm by 16 cm in order to make a tent for her little sister's doll using the dimensions for the tent shaped as a triangular prism how much fabric will be left over

324 cm 2
240 cm 2
184 cm 2
84 cm 2

First, calculate the total fabric needed to make the triangular prism tent.

Base area = 6 cm x 7 cm = 42 cm^2
Lateral surface area = (4 cm x 12 cm) + (6 cm x 7 cm) + (7 cm x 12 cm) = 48 cm^2 + 42 cm^2 + 84 cm^2 = 174 cm^2

Total fabric needed = 42 cm^2 + 174 cm^2 = 216 cm^2

Fabric left over = Total fabric purchased - Total fabric needed
Fabric left over = 16 cm x 16 cm - 216 cm^2 = 256 cm^2 - 216 cm^2 = 40 cm^2

Therefore, there will be 40 cm^2 of fabric left over.
