Find a cube's volume, surface area and diagonal.

Volume 64

Surface area 96

Space diagonal 6.928

Formula: volume = a³ ; surface = 6a²

Step-by-step with your numbers:

1. Values used:

2. Edge length = 4

4. Volume = Edge length cubed = 4 x 4 x 4 = 64

5. Surface area = 96

6. Space diagonal = 6.928

Did we solve your problem today?

All cube measurements from one edge.

The math behind it

Volume = a³. Surface area = 6a². Space diagonal = a√3.

Edge 4 → volume 64, surface 96.

Space diagonal?

The longest straight line inside the cube, corner to corner.
