Question

find l. s a of cuboid whose 1 6 cm b 4 cm h 10 cm ​

Answer 1

Answer:

Given :-

• A cuboid whose length is 6 cm, breadth is 4 cm and height is 10 cm.

To Find :-

• What is the L.S.A. or lateral surface area of cuboid.

Formula Used :-

$\clubsuit$ Lateral Surface Area or L.S.A. of Cuboid :

$\bigstar \: \: \sf\boxed{\bold{L.S.A._{(Cuboid)} =\: 2h(l + b)}}\: \: \: \bigstar$

where,

• L.S.A. = Lateral Surface Area
• l = Length
• b = Breadth
• h = Height

Solution :-

Given :

• Length = 6 cm
• Breadth = 4 cm
• Height = 10 cm

According to the question by using the formula we get,

$\implies \bf L.S.A._{(Cuboid)} =\: 2h(l + b)$

$\implies \sf L.S.A._{(Cuboid)} =\: 2 \times 10(6 + 4)$

$\implies \sf L.S.A._{(Cuboid)} =\: 20(6 + 4)$

$\implies \sf L.S.A._{(Cuboid)} =\: 20(10)$

$\implies \sf L.S.A._{(Cuboid)} =\: 20 \times 10$

$\implies \sf\bold{\underline{L.S.A._{(Cuboid)} =\: 200\: cm^2}}$

$\therefore$ The L.S.A. or lateral surface area of cuboid is 200 cm² .
