that there is no wastage of iron?​

Answer 1

Answer:

220

Step-by-step explanation:

Answer 2

Answer:

vol of cuboid= lxbxh

l=3.3

b=2.4

h=0.75

vol= 3.3×2.4×0.75

vol= 5.94m^3

vol of cube = a^3

vol of cube = 0.30×0.30×0.30

vol of cube= 0.027

total no cube obtain= vol of cuboid ÷ vol of cube

total cube= 5.94÷0.027

total cube= 220
