Question

Which expressions will help you find the surface area of this right triangular prism? Select all that apply.

A) 3 cm
B) 5 cm
C) 11 cm
D) 4 cm

Answer 1

To find the surface area of a right triangular prism, calculate the area of each face and sum them up using the given dimensions.

Step-by-step explanation:

To find the surface area of a right triangular prism, we need to calculate the area of each face and then sum them up. In this case, the triangular faces have a base of 3 cm and a height of 5 cm. The rectangular face has a length of 11 cm and a width of 4 cm. So the expressions that will help us find the surface area are:

1. Area of triangular face: 0.5 * 3 cm * 5 cm
2. Area of rectangular face: 11 cm * 4 cm

Therefore, the expressions A) 3 cm, C) 11 cm, and D) 4 cm will help us find the surface area of this right triangular prism.
