Solution Steps

00:00 Calculate the volume of the cube if possible
00:03 In a cube all edges are equal, let's mark it as A
00:07 We'll use the formula to calculate the base area (edge squared)
00:10 We'll find the square root and get 2 possible solutions
00:15 A must be positive, as it's the length of an edge
00:19 This is the size of edge A
00:23 We'll use the formula to calculate volume (edge cubed)
00:30 We'll substitute the edge value we found and solve for volume
00:34 And this is the solution to the problem

Step-by-Step Solution

To determine if it is possible to calculate the volume of the cube and then find it, we proceed as follows:

  • Step 1: Identify the given information
    The base area of the cube is given as 16cm2 16 \, \text{cm}^2 .
  • Step 2: Apply the appropriate formula for the side length
    Since the base of a cube is a square, we have s2=16 s^2 = 16 , where s s is the side length.
  • Step 3: Calculate the side length
    Solving for s s , we find s=16=4cm s = \sqrt{16} = 4 \, \text{cm} .
  • Step 4: Calculate the volume of the cube
    The volume V V of a cube with side s s is V=s3 V = s^3 . Substituting in the side length, we get V=43=64cm3 V = 4^3 = 64 \, \text{cm}^3 .

Therefore, it is possible to calculate the volume of the cube, and the volume is 64cm3 64 \, \text{cm}^3 .
