Question

pls help me in maths

Answer 1

Step-by-step explanation:

a) vol = 300 cubic cm

b) vol = (20% of 300) + 300

= 360 cubic cm

c) no. of salt pots filled from standard box= 300/10 = 30

So, we can say that each salt pot has vol. 30 cubic cm ,

So, no. of salt pots filled from special offer box = 360/30 = 12 .

d) total surface area = 2( lb + lh + bh )

= 280 sq cm

Hope it helps you ✌️
