For tin can with rectangular 6 base. 

l = 5 cm, b = 4 cm, h = 15 cm 

Volume of the tin can = lbh = 5 × 4 × 15 cm3 = 300 cm3 

For plastic cylinder with circular base. 

r = 7/ 2 cm = 3.5 cm, h = 10 cm 

Volume of the plastic cylinder = π r2h 

= 22/ 7 × 3.5 × 3.5 × 10 cm3 = 385 cm3 

Difference in the capacities of the two containers 

= (385 – 300) cm3 = 85 cm3 

Hence, the plastic cylinder with circular base has greater capacity by 85 cm3 Ans.

The concentration of hydrogen ion in a sample of soft drink is 3.8 × 10–3M. What is its pH?

pH = – log[3.8 × 10–3 ]  = – {log[3.8] + log[10–3 ]}  = – {(0.58) + (– 3.0)}  = – {– 2.42} = 2.42  Therefore, the pH of the soft drink is 2.42...
