Grade: 4-a Lesson: S3-L7 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find the volume of a square pyramid whose height is 27 units and the edge of the base is 10 units. |
|
2 |
Step |
The given values are |
h = 27 units and b = 10 units |
3 |
Step |
To find the volume of a square pyramid formula is |
\$"V_square-pyramid" = 1/3 times s^2 times h\$ |
4 |
Step |
Now plug the values in the formula |
\$"V_square-pyramid" = 1/3 times 10^2 times 27\$ |
5 |
Step |
After simplification |
\$"V-square-pyramid" = 1/3 times 100 times 27\$ \$"V_sqaure-pyramid" = 2700/3\$ \$"V_sqaure-pyramid" = 900 \$ cum.units |
6 |
Step |
Therefore, the volume of the square pyramid is \$900 units^3\$. |

8 |
Choice.A |
This is incorrect because it seems to have used only the base area |
90 cu.units |
9 |
Choice.B |
This is not correct because it provides an incorrect value for the volume |
9000 cu.units |
10 |
Choice.C |
This is correct because it correctly calculates the volume of the square pyramid |
900 cu.units |
11 |
Choice.D |
This is not correct because it provides an incorrect value for the volume |
9 cu.units |
