Question

find TSA of cuboid with l = 10 cm 5cm 3cm​

Answer 1

Answer:

Formula for total surface area of a cuboid is

2(lb + bh +lh)

Given,

l = 10 cm

b = 5 cm

h = 3 cm

By putting these in formula, we get ;

2(10 X 5 + 5 X 3 + 3 X 10)

2( 50 + 15 + 30)

2 X 95

190

Answer 2

Answer:

$\bf\blue{Question}$

Find TSA of cuboid with l = 10 cm b = 5cm h = 3cm

$\bf\blue{Given}$

Length = 10 cm

Breadth = 5 cm

Height = 3 cm

$\bf\blue{What\:to\: find?}$

T.S.A. ( Total Surface Area ) of the cuboid.

$\bf\blue{Formula}$

T.S.A. of cuboid = 2 ( lb + lh + bh) sq. units.

$\bf\blue{Solution}$

According to question:-

T.S.A. of cuboid = 2 ( lb + lh + bh) sq. units.

$2 \times [(10 \times 5) + (10 \times 3) + (5 \times 3)]$

$2 \times[ 50 + 30 + 15]$

$2 \times [95]$

$190$

•°• T.S.A. of cuboid is 190 cm²
