Question

find t.s.a of given cuboid l=10m,b=25m,h=15m​

Answer 1

Answer:

1550 cm sq.

Step-by-step explanation:

total surface area - 2(lb+bh+lh)

= 2×( 250 +375+ 150)

= 2×775

= 1550 cm sq.

Answer 2

Answer:

Given :-

• A cuboid whose length is 10 m, breadth is 25 m and height is 15 m.

To Find :-

• What is the TSA or total surface area of cuboid.

Formula Used :-

$\clubsuit$ Total Surface Area or T.S.A. of Cuboid :

$\bigstar \: \: \sf\boxed{\bold{\pink{T.S.A._{(Cuboid)} =\: 2(lb + bh + hl)}}}\: \: \: \bigstar$

where,

• T.S.A. = Total Surface Area
• l = Length
• b = Breadth
• h = Height

Solution :-

Given :

• Length = 10 m
• Breadth = 25 m
• Height = 15 m

According to the question by using the formula we get,

$\implies \bf T.S.A._{(Cuboid)} =\: 2(lb + bh + hl)$

$\small \implies \bf T.S.A._{(Cuboid)} =\: 2\bigg\{(10 \times 25) + (25 \times 15) + (15 \times 10)\bigg\}$

$\small \implies \sf T.S.A._{(Cuboid)} =\: 2\bigg\{(250) + (375) + (150)\bigg\}$

$\small \implies \sf T.S.A._{(Cuboid)} =\: 2\bigg\{250 + 375 + 150\bigg\}$

$\small \implies \sf T.S.A._{(Cuboid)} =\: 2\bigg\{625 + 150\bigg\}$

$\small \implies \sf T.S.A._{(Cuboid)} =\: 2\bigg\{775\bigg\}$

$\small \implies \sf T.S.A._{(Cuboid)} =\: 2 \times 775$

$\small \implies \sf\bold{\red{T.S.A._{(Cuboid)} =\: 1550\: m^2}}$

$\small \sf\bold{\purple{\underline{\therefore\: The\: total\: surface\: area\: or\: TSA\: is\: 1550\: m^2\: .}}}$
