|---|---|---|---|
1 |
Problem |
Find the volume of a cube whose length of the longest diagonal is \$5\sqrt3\$ cm. |
|
2 |
Step |
The given value |
length = \$5\sqrt3\$ cm |
3 |
Formula: |
Volume of cube |
\$V = a^3\$ |
4 |
Hint |
Here we find out the a value |
\$\sqrt 3a = l\$ |
5 |
Step |
Now substitute the values |
\$\sqrt3a = 5\sqrt3\$ |
6 |
Step |
After simplification |
\$a = (5\sqrt 3) / (\sqrt 3)\$ |
7 |
Step |
After simplification |
a = 5 cm |
8 |
Step |
Now substitute the values |
\$V = 5^3\$ |
9 |
Step |
After simplification |
\$V = 125 cm^3\$ |
10 |
Step |
The volume of cube is \$V = 125 cm^3\$ |
