How many cubes of edge 2 dm can be cut out of a meter cube?
Correct answer: D. 125
- A. 50
- B. 64
- C. 216
- D. 125
Explanation
A metre cube has side 10 dm. Along each dimension, 10 dm ÷ 2 dm = 5 cubes fit, so the total number is 5 x 5 x 5 = 125 cubes. Option b, 64, can result from using an incorrect side division or from not cubing the number that fits along one dimension.

About Area and Volume
Area measures the surface enclosed by two-dimensional figures, while volume measures the space occupied by three-dimensional solids. Problems use formulas for rectangles, triangles, circles, prisms, cylinders, cones, spheres, and composite figures, including unit conversion and the distinction between surface area, lateral area, and volume.
