Question

1 A chocolate bar measures 10 cm long by 2 cm wide and is 2 cm thick.

a) Calculate the volume of one bar.

b) pendulum makes 10 complete oscillations in 8 seconds. Calculate the time period of the pendulum.

c) How many bars each 2 cm long, 2 cm wide and 2 cm thick have the same total volume?

Answer 1

A) Volume of cuboid = length *breadth*height
=10*2*2=40cm^3


B)time period of one pendulum = no.of oscillations/time= 10/8= 5/4



C) 3 bars
