If the sides of a slab simply supported on edges and spanning in two directions are equal, the maximum bending moment is multiplied by A. 0.2 B. 0.3 C. 0.4 D. 0.5

The correct answer is $\boxed{\text{B) 0.3}}$.

The maximum bending moment in a simply supported slab spanning in two directions is given by the following equation:

$$M = \frac{w l^2}{8}$$

where $w$ is the uniform load per unit area, $l$ is the length of the slab, and $b$ is the width of the slab.

If the sides of the slab are equal, then the length and width of the slab are equal, and the maximum bending moment is given by:

$$M =
