Virginia beach is 15 kilometers wide and 50 kilometers long. if 2 cm of rain falls on virginia beach, how many cubic meters of rain fell on virginia beach?

Assume that the shape of Virginia beach is rectangular.

Note that

1 km = 10³ m

1 cm = 10⁻² m

The area is

A = (15 km) * (50 km)

= (15 x 10³ m) * (50 x 10³ m)

= 7.5 x 10⁸ m²

Because 2 cm of rain fell, the volume is

V = (7.5 x 10⁸ m) * (2 x 10⁻² m) = 1.5 x 10⁶ m³

Answer: 1.5 x 10⁶ m³
