Answer 1

Considering each part of the prism and it's dimensions, the surface area of the prism is of 127 cm².

What is the surface area of a figure?

It is the sum of the areas of all faces of the figure.

In this problem, the figure is composed by:

• Two right rectangular faces, with legs 5 cm and 12 cm.

• One rectangular face, with sides 6 cm and 12 cm.

• One square face, with side of 5 cm.

The measures are in cm, hence the areas will be in square centimeters. The separate areas are given by:

• $A_1 = 0.5 \times 5 \times 12 = 30$.

• $A_2 = 6 \times 12 = 72$.

• $A_3 = 5^2 = 25$.

Then, the surface area of the prism is given by:

S = 30 cm² + 72 cm² + 25 cm² = 127 cm².
