Question

aflati aria totala si volumul cuboidului cu deminaiunea de 15cm 10cm 8cm​

Answer 1

$A _{t} = 2 \times ( lL + Lh + lh)$

$A _{t} = 2 \times (10 \times 15 + 15 \times 8 + 10 \times 8)$

$A _{t} = 2 \times (150 + 120 + 80)$

$A _{t} = 2 \times 350 = 700 {cm}^{2}$

$V = L \times l \times h$

$V = 15 \times 10 \times 8$

$V = 1200 {cm}^{3}$
