Question

Pls help! I really need help! This is the question..

A sample of iron has dimensions of 2 cm x 4 cm x 6 cm and a mass of 100g. What is the density of the sample?

Answer 1

2.083 g/
`cm^(3)`

Explanation:

Density is mass / volume

volume = length * width * height

(In this case since iron is usually in a block unless stated otherwise)

100g / (2*4*6)cm^3 = density

100g /
`48 cm^(3)` = 2.083 g/
`cm^(3)`
