If an object has 2 mililiters of volume and 10g calculate the density, the g = grams.

Density is the ratio of the mass to the volume of a body

so:

Density = 10 (gram) ÷ 2 (ml) = 5 gram/ml

hope that helps

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
