Question

Va rog ajutati-mă cu exercitiul 22B si 23

Answer 1

$22)b)L = 1 \: dm$

$l = \frac{L}{2}$

$l = \frac{1}{2}$

$l = 0.5 \: dm$

$h = \frac{L}{4}$

$h = \frac{1}{4}$

$h = 0.25 \: dm$

$V=L \times l \times h$

$V=1 \times 0.5 \times 0.25$

$V=0.125 \: {dm}^{3}$

$23)a)1 \: m = 10 \: dm$

$b)0.25 \: {cm}^{3} = 250 \: {mm}^{3}$

$c)1 \: ha = 10 \: 000 \: {m}^{2}$

$12847 \: {m}^{2} = 1.2847 \: ha$
