Question

Alice is building a caterpillar habitat for some caterpillars she found in her backyard. She plans to cover all sides of the habitat with screen so the caterpillars get plenty of fresh air. The measurements are 0.8, 1, 0.4. What is the total amount of screen that Alice will need for her habitat?

a) 1.4 square units
b) 0.8 square units
c) 0.32 square units
d) 2.2 square units

Answer 1

To find the total amount of screen needed for the caterpillar habitat, multiply the length and width of each side and add them together. The total amount of screen needed is 2.2 square units.

Step-by-step explanation:

To find the total amount of screen that Alice will need for her caterpillar habitat, we need to calculate the surface area of each side and then add them together. The measurements given are 0.8, 1, and 0.4. To find the surface area of a rectangular side, multiply the length and width. The first side has dimensions 0.8 x 1, the second side has dimensions 1 x 1, and the third side has dimensions 0.4 x 1. Add up the surface areas of all three sides to get the total amount of screen needed for the habitat.

Surface Area of Side 1 = 0.8 x 1 = 0.8 square units

Surface Area of Side 2 = 1 x 1 = 1 square unit

Surface Area of Side 3 = 0.4 x 1 = 0.4 square units

Total Amount of Screen Needed = Surface Area of Side 1 + Surface Area of Side 2 + Surface Area of Side 3 = 0.8 + 1 + 0.4 = 2.2 square units
