Question

How many wooden cubic blocks, each side of 2 cm, should be arranged to form a cuboid with dimemsions 10 dm × 8 dm × 40 cm.

Answer 1

Answer:

9

Step-by-step explanation:

1dm = 10cm

hence,

volume of cuboid = 1cm × 0.8cm × 40cm

72

volume of cubic block = 2×2×2

8cm

no of cube block that will fit in cuboid = 72/8= 9

ANS = 9 cubic blocks

Answer 2

Answer:

40000

Step-by-step explanation:

${a}^{3} n = lbh \\( {2})^{3} n= 100 \times 80 \times 40 \\ 8n = 100 \times80 \times 40 \\ n = \frac{100 \times 80 \times 40}{8} \\ n = 40000$
