Sarah is making a model tint how much material will she need explain the process to solve and show all calculations. The initials 5 cm 5 cm 3 cm 4 cm and 14 cm explain
To calculate the amount of material needed to make the model tent, we must first calculate the surface area of each of the five sides of the tent.
The tent has the following dimensions:
- Base: 5 cm x 5 cm = 25 cm^2 (two sides with this dimension)
- Two sides with the dimensions 5 cm x 3 cm = 15 cm^2 each
- The front side with dimensions 4 cm x 3 cm = 12 cm^2
- The top side with dimensions 5 cm x 4 cm = 20 cm^2
Now, add up all the surface areas:
2(25 cm^2) + 2(15 cm^2) + 12 cm^2 + 20 cm^2 = 50 cm^2 + 30 cm^2 + 12 cm^2 + 20 cm^2 = 112 cm^2
Therefore, Sarah will need 112 square centimeters of material to make the model tent.
