Question

How many wooden blocks of dimensions 6.4cm × 4.2cm × 1cm can be cut from a log of wood of dimensions 56cm × 8cm × 6cm , assuming that there is no wastage ?​​

Answer 1

Answer:

100

Step-by-step explanation:

volume of each wooden block= L×B×H=26.88

volume of wood=2688

numbers of wood=2688÷26.88=100

Answer 2

$no \: of \: wooden \: blocks = \frac{volume \: of \: wood \: log}{volume \: of \: wooden \: block} \\ no \: of \: woodnblocks = \frac{56 \times 8 \times 6}{6.4 \times 4.2 \times 1} \\ = \frac{560 \times 80 \times 6}{64 \times 42 \times 1 } \\ = \frac{268800}{2688} \\ = 100$
