A cuboidal block of solid iron has dimensions 50 cm, 45 cm, and 34 cm, how many cuboids of size 5 cm by 3 cm by 2 cm can be obtained from this block? Assume cutting causes no wastage.
Answer:
Given details are,
Dimensions of cuboidal block of iron is = 50cm × 45cm × 34cm
Size of small cuboids cutting from it is = 5cm × 3cm × 2cm
So,
Number of small cuboids that can be cut =
Volume of large iron cuboid/ volume of small cuboid
= (50 × 45 × 34) / (5 × 3 × 2)
= 2550 cuboidal blocks
