Remember: Density = Mass Volume
Volume = Length x Width x Height (mL is also a measure of volume)
a Density of a wood cube with 3 cm per side that has a mass of 81 grams
b. Density of a lead cube with 5 cm per side that has a mass of 400 grams
a Density of Liquid A that has a volume of 100 mL and a mass of 200 grams
Density of a
Density of b
Density of c

A. 3g/cm³

B. 3.2g/cm³

C. 2g/cm³

Explanation:

A. Density = mass ÷ volume

Volume = length × width × height

Where;

Mass = 81grams, length = 3cm

Volume= 3cm × 3cm × 3cm = 27cm³

Density = 81/27

Density = 3g/cm³

B) Volume = length × width × height

Where;

Mass = 400grams, length = 5cm

Volume= 5cm × 5cm × 5cm = 125cm³

Density = 400/125

Density = 3.2g/cm³

C) Volume = 100mL

Where;

Mass = 200grams

Density = 200/100

Density = 2g/cm³
