The oblique pyramid has a square base with an edge length of 5 cm. The height of the pyramid is 7 cm.

What is the volume of the pyramid?

A. [tex]\( 11 \frac{2}{3} \, \text{cm}^3 \)[/tex]
B. [tex]\( 43 \frac{3}{4} \, \text{cm}^3 \)[/tex]
C. [tex]\( 58 \frac{1}{3} \, \text{cm}^3 \)[/tex]
D. [tex]\( 87 \frac{1}{2} \, \text{cm}^3 \)[/tex]



Answer :

Let's solve the problem step-by-step.

Given:
- The edge length of the square base of the pyramid is 5 cm.
- The height of the pyramid is 7 cm.

First, we need to find the area of the square base. The formula for the area of a square is:

[tex]\[ \text{Area} = \text{side}^2 \][/tex]

In this case:

[tex]\[ \text{Area} = 5 \, \text{cm} \times 5 \, \text{cm} = 25 \, \text{cm}^2 \][/tex]

Now that we have the area of the base, we can use it to find the volume of the oblique pyramid. The volume [tex]\( V \)[/tex] of a pyramid is calculated using the formula:

[tex]\[ V = \frac{1}{3} \times \text{Base Area} \times \text{Height} \][/tex]

Substituting the given values:

[tex]\[ V = \frac{1}{3} \times 25 \, \text{cm}^2 \times 7 \, \text{cm} \][/tex]

[tex]\[ V = \frac{1}{3} \times 175 \, \text{cm}^3 \][/tex]

[tex]\[ V = 58.33333333333333 \, \text{cm}^3 \][/tex]

We can express the volume as a proper fraction. Noting that 58.3333... is equivalent to 58 and one-third:

[tex]\[ V = 58 \frac{1}{3} \, \text{cm}^3 \][/tex]

Therefore, the correct answer among the options provided is:

[tex]\[ \boxed{58 \frac{1}{3} \, \text{cm}^3} \][/tex]
