Problem |
A rectangular prism has dimensions of length 5 cm, width 4 cm, and height 3 cm. What is the surface area of the rectangular prism? |
|
2 |
Step |
The given values are |
l = 5 cm , w= 4 cm and h = 3 cm |
3 |
Formula: |
The surface area of rectangle prism |
\$Surface Area = 2lw + 2lh + 2wh\$ |
4 |
Step |
Now substitute the values |
\$Surface area = 2 times 5 times 4 + 2 times 5 times 3 + 2 times 4 times 3\$ |
5 |
Step |
After simplification |
\$surface area = 40 + 30 + 24\$ |
6 |
Step |
After simplification |
Surface Area = 94 square cm |
7 |
Step |
The surface area of the rectangular prism is 94 square centimeters. |

Sumup |
Can you summarize what you’ve understood in the above steps? |
|
9 |
Choice.A |
This is incorrect because the units are consistent, but there’s an error in the calculations |
\$49 cm^2\$ |
10 |
Choice.B |
49 cm is not correct because the surface area is measured in square units (cm²), not linear units (cm) |
49cm |
11 |
Choice.C |
49 cm is not correct because the surface area is measured in square units (cm²), not linear units (cm) |
96 cm |
12 |
Choice.D |
This is correct because the units are consistent, and the calculations done accurately |
\$94 cm^2\$ |
