Question

the lenght qnd breath and height of a cuboid are 20 cm ,15cm ,10 cm respectively​

Answer 1

Answer

Given :-

Length = 20cm

Breadth = 15cm

Height = 10cm

Total surface of cuboid :-

$2(lb + bh + hl) \\ 2(20 \times 15 + 15 \times 10 + 10 \times 20) \\ 2(300 + 150 + 200) \\ 2(650) = 1300 {cm}^{2}$

Lateral surface of cuboid :-

$2h(l + b) \\ 2 \times 10(20 + 15) \\ 20(35) = 700 {cm}^{2}$

Volume of cuboid :-

$l \times b \times h \\ 20 \times 15 \times 10 = 3000 {cm}^{3}$
