There is a steel cube 5 cm by 5 cm by 5 cm. Its mass (measured on a balance) is 975 grams.
- What is its volume? cm3
- What is the mass density of the steel? g/cm3
Correct Answer
(1) 125
(2) 7.8
Explanation
Remember the volume = width x hight x depth = 5 x 5 x 5 = 125 cm3
Mass density = \(\frac{975\text{ } g}{125\text{ } cm^3} = 7.8\) g/cm3
