Sara is making a model tent. How much material will she need? Explain the process to solve and show all calculations.
To determine how much material Sara will need for her model tent, she will need to calculate the surface area of the tent.
Let's assume the model tent is a simple rectangular prism with dimensions:
Length = 10 cm
Width = 8 cm
Height = 5 cm
To calculate the amount of material needed, Sara will first find the surface area of the tent. The surface area of a rectangular prism can be calculated using the formula:
Surface Area = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height of the tent.
Surface Area = 2(10 cm x 8 cm) + 2(10 cm x 5 cm) + 2(8 cm x 5 cm)
Surface Area = 2(80 cm^2) + 2(50 cm^2) + 2(40 cm^2)
Surface Area = 160 cm^2 + 100 cm^2 + 80 cm^2
Surface Area = 340 cm^2
Therefore, Sara will need 340 square centimeters of material for her model tent.
