Question

what is the area of the triangular prism net where the triangle measures 8cm at the case and 6.9 for height. The three rectangular nets measure a base of 8cm and a height of 6cm? Round the answer to the nearest tenth

Answer 1

To find the area of the triangular prism net, we need to calculate the area of each individual shape and then add them together.

1. The area of the triangle:
Area = 0.5 x base x height
Area = 0.5 x 8cm x 6.9cm
Area = 27.6 cm²

2. The area of each rectangular net:
Area = base x height
Area = 8cm x 6cm
Area = 48 cm²

3. Since there are three rectangular nets, the total area of all three is:
Total area of all three rectangular nets = 3 x 48 cm² = 144 cm²

4. Now, we add the areas of the triangle and the three rectangular nets:
Total area = 27.6 cm² + 144 cm²
Total area = 171.6 cm²

Therefore, the area of the triangular prism net is approximately 171.6 cm².
