Question

Length breath and height of a cuboid shape box of medicine is 20 cm ,12cm and 10 cm respect truly find the surface area of vertical faces and total surface area of vertical faces and total surface area of this Bo's

Answer 1

Answer:

Step-by-step explanation:

Lateral surface area=2H(L+B)

=20(32)

=640cm²

Total surface area=2(lh+bh+lb)

=2(200+120+240)

=1120cm²

Hope it helps you!

Answer 2

$\huge\bold{\mathtt{\purple{✍︎A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍︎}}}}}}}}}}}}}$$\huge \Rightarrow$

$\Large \bold \red{Solution}\Rightarrow$

$\bold {Given:}\rightarrow$

Here, length = 20 cm, breadth = 12 cm,

height = 10 cm.

The surface area of the vertical faces of the box.

$\Rightarrow 2(l+b)×h$ ...(Formula)

$\Rightarrow 2(20+12) ×10$

$\Rightarrow 2×32×10$

$\Rightarrow \fbox {640 cm²}$

The total surface area of the box

$\Rightarrow 2(lb+bh+lh)$

$\Rightarrow (20×12+12×10+20×10)$

$\Rightarrow 2(240+120+200)=2(560)$

$\Rightarrow \fbox {1120 cm²}$

$\Large\bold\green{Ans} \Longrightarrow$

The surface area of the vertical faces of the box is 640 cm² and the total surface area is 1120 cm².
