Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
If the length, breadth and height of a cuboid are 11 cm, 16 cm and 19 cm, then find its total surface area and find the volume of cuboid. |
|
2 |
Step |
The given values are |
l = 11 cm , b = 16 cm and h = 19 cm |
3 |
Formula |
To find the total surface area and volume of a cuboid, you can use the following formulas |
\$"TSA" = 2 ("lw" + "lh" + "wh")\$ |
4 |
Step |
Now plug the value in the formula |
\$"TSA" = 2(11 times 16 + 11 times 19 + 16 times 19)\$ \$"TSA" = 2( 176 + 209 + 304)\$ \$"TSA" = 2 times 689\$ TSA = 1378 sq.cm |
5 |
Step |
To find the volume of the cuboid formula is |
\$V = l times w times h\$ |
6 |
Step |
Now plug the value in the formula |
\$V = 11 times 16 times 19\$ V = 3344 cu.cm |
7 |
Step |
Therefore, the lateral surface area and volume of the cuboid are \$1378 cm^2\$ and \$3344 cm^2\$. |

SumUp |
Can you summarize what you’ve understood in the above steps? |
|
9 |
Choice.A |
This answer is right as it gives the accurate measurements for both the cuboid’s total surface area and volume |
1378 sq.cm and 3344 cu.cm |
10 |
Choice.B |
This is incorrect because it provides incorrect values for both the total surface area and volume of the given cuboid |
1378 sq.cm and 3434 cu.cm |
11 |
Choice.C |
This is not correct because the total surface area mentioned (1387 sq. cm) is incorrect |
1387 sq.cm and 3344 cu.cm |
12 |
Choice.D |
This is incorrect because it provides incorrect values for both the total surface area and volume of the given cuboid |
1387 sq.cm and 3434 cu.cm |
