Solution -

$given - \\ l = 16m \\ b = 14m \\ h = 7m \\ \\ \\ v = l \times b \times h \\ \: \: \: \: \: \: 16 \times 14 \times 7 \\ \: \: \: \: \: \: \: \: = 1568 {m}^{3} \\ \\ tsa = 2(lb + bh + hl) \\ \: \: \: \: \: \: \: = 2(16\times 14 + 14 \times 7 + 7 \times 16) \\ \: \: \: \: \: \: \: = 2(224 + 98 + 112) \\ \: \: \: \: \: \: \: = 2 \times 434 \\ \: \: \: \: \: \: \: = 868 {m}^{2}$
