Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Calculate the side length of the square base.
  • Step 2: Calculate the area of the square base.
  • Step 3: Compute the volume of the cuboid using the area and height.

Let's work through each step:

Step 1: The perimeter of the square base is given as 12 cm. We can find the side length s s of the square using the perimeter formula:

P=4s P = 4s

So,

12=4s 12 = 4s which implies s=124=3 cm s = \frac{12}{4} = 3 \text{ cm} .

Step 2: The area of the square base is then:

Area=s2=32=9 cm2 \text{Area} = s^2 = 3^2 = 9 \text{ cm}^2 .

Step 3: To find the volume of the cuboid, we use the formula for volume:

V=Base Area×Height=9×8=72 cm3 V = \text{Base Area} \times \text{Height} = 9 \times 8 = 72 \text{ cm}^3 .

Thus, we have successfully determined that it is possible to calculate the volume of the cuboid, and the volume is 72 cm3 72 \text{ cm}^3 .

Therefore, the correct answer to the problem is Yes.
