Answer:

0.0118125 (kg)

Explanation:

mass = density x volume

First, find the volume of the cube as you're already given the density. You're also given the length of the cube, 1.5 cm. You need to convert this to m since the density's unit is kg/m^2

1.5cm x (1m/100cm) = 0.015m

Since Volume = (length)^3,

Volume of the cube = (0.015)^3

Volume of the cube = 3.375*10^-6

So mass of the cube = (3500)(3.375*10^-6) = 0.0118125 (kg)
