Answer:
Volume = 112cm^2
Density = 0.45 g/cm^2 (2.s.f)
Explanation:
Volume of a cube is found by multiplying its height by its length by its width.
We are given the values: l = 7cm, w = 8cm, h = 2cm, so to find the volume we just need to multiply them all together:
V=lwh
V = (7)(8)(2)
The volume of the cube = 112cm^2
Density is found by dividing mass by volume.
We are given the mass (50 grams) and we have just found the Volume (112cm^2), so we can just divide them to find the density:
p (symbol for density) = m/v
p = (50)(112)
The density of the cube is 0.45 g/cm^2 (2.s.f.)
Hope this helped!
