To find the amount of material Sara will need to make a model tent, we first need to calculate the surface area of the tent.
The tent has 5 sides - a base, 2 sides, a front, and a back. To find the surface area of each side, we need to calculate the area of each side:
Base: 15 cm x 5 cm = 75 cm^2
Front and back: 15 cm x 3 cm = 45 cm^2 (each)
Sides: 5 cm x 4 cm = 20 cm^2 (each)
Now we calculate the total surface area of the tent:
Base: 75 cm^2
Front and back: 45 cm^2 (each) = 90 cm^2
Sides: 20 cm^2 (each) = 40 cm^2
Total surface area = 75 cm^2 + 90 cm^2 + 40 cm^2 = 205 cm^2
Therefore, Sara will need 205 cm^2 of material to make her model tent.
Sara is making a model tent. How much material will she need?
