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)
