How do you calculate the volume of a rectangular solid?

• length x width x height
• mass divided by volume
• with a triple beam balance
• it's impossible

Answer explanation

A block of wood has a length of 12 cm, width of 7 cm, and height of 5 cm.

What is the volume? (Use a calculator)

• 410 cm³
• 420 cm³
• 402 cm³
• 401 cm³

Answer explanation

Length = 12 cm, Width = 7 cm, Height = 5 cm

Use the following formula:

Volume=(Length)x(Width)x(Height)

Volume = (12 cm) x (7 cm) x (5 cm)

Volume = 420 cm^3

A cube has a length of 10 feet, width of 7 feet, and height of 16 feet.

What is the volume?

• 1120 ft²
• 2011 ft²
• 120 ft³
• 1120 ft³

Answer explanation

Length = 10 ft, Width = 7 ft, Height = 16 ft

Use the following formula:

Volume=(Length)x(Width)x(Height)

Volume = (10 ft) x (7 ft) x (16 ft)

Volume = 1120 ft^3

Why do we use this device?

Answer explanation

An object has a volume of 200cm³ and its mass is 400g. What is its density?

• 2g/cm³

• 2kg/m³

• 20g

• 20kg

Answer explanation

Volume = 200 cm^3

Mass = 400 grams

Density = (400 grams)/(200 cm^3)

Density = 2 grams/cm^3
