Question

Va rog frumos ajutatima am test la matematica.

Answer 1

$L = 14 \: cm$

$l = 5.5 \: cm$

$h = 10 \: cm$

$A_{t} = 2(Lh + lh + Ll)$

$A_{t} = 2(14 \times 10 + 5.5 \times 10 + 14 \times 5.5)$

$A_{t} = 2(140 + 55 + 77)$

$A_{t} = 2 \times 272$

$A_{t} = 544 \: {cm}^{2}$

$V=L \times l \times h$

$V=14 \times 5.5 \times 10$

$V=770 \: {cm}^{3}$
