Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find the volume, and lateral surface area of a cube each of whose 14 m edges measures. |
|
2 |
Step |
The given value is |
a = 14 m |
3 |
Formula |
To find the lateral surface area of a cube is |
\$"LSA" = 4 times a^2\$ |
4 |
Step |
Now plug the value in the formula |
\$"LSA" = 4 times (14)^2\$ \$"LSA" = 4 times 196\$ LSA = 784 sq.m |
5 |
Step |
To find the volume of a cube is |
\$"V" = "a"^3\$ |
6 |
Step |
Now plug the value in the formula |
\$"V" = (14)^3\$ V = 2744 cu.m |
7 |
Step |
Therefore, the lateral surface area and volume of the cube are \$784 m^2\$ and \$2744 m^3\$. |
