What is the surface area of the prism?

A rectangular prism with a length of 3 meters, width of 4 meters, and height of 2 meters.

a

18 square meters

b

24 square meters

c

52 square meters

d

64 square meters

To find the surface area of ANY prism you need to find the area of individual shape first.

To find 2 faces of the prism, you will need to do bxh. As there is 2 of the same rectangle, you need to multiply it by 2. Therefore, the first number you need is 16m squared.

To find the next part of the prism, you will need to do 2m x 3m which is 6m. You need the area so 6m squared (The units are important). There are also 2 of these, so multiply it by 2 to get 12m squared.

For the final part of the prism, you will need to do 4m x 3m which is 12m squared. There are 2 of these so the it is 24m squared.

Finally, you will need to add all these figures up.

16m squared + 12m squared + 24m squared = 52m squared
