Sara is making a model tent. How much material will she need? Explain the process to solve and show all calculations.

w=4 depth=15 v=3 height=5

To calculate the amount of material Sara will need to make the model tent, you need to calculate the surface area of the tent.

The formula for the surface area of a rectangular prism (which a tent can be modeled as) is: 2lw + 2wh + 2lh, where l = length, w = width, and h = height.

Given:
- Width (w) = 4
- Height (h) = 5
- Depth (l) = 15

Plug in the values into the formula:
Surface Area = 2(4)(15) + 2(4)(5) + 2(15)(5)
Surface Area = 120 + 40 + 150
Surface Area = 310 square units

Therefore, Sara will require 310 square units of material to make the model tent.
