Question

Find the total surface area of a cuboid if its
length is 5m, breadth is 3 m and height is
50 cm​

Answer 1

Answer:

Total Surface Area = 38 m²

Step-by-step explanation:

Length = 5m

Breadth = 3m

Height = 50cm = 0.5m

Total Surface Area = 2(lb+bh+hl)

= 2(5*3+3*0.5+0.5*5)

= 2(15+1.5+2.5)

= 2 * 19

= 38m²

Answer 2

$\huge \mathbb{ANSWER:-}$

let me call total surface area as TSA

$TSA = 2(lb +lh + hb)$

before we should convert length into m

1m = 100cm

50cm = 1/2m = 0.5

$= 2((5 \times 3) + (5 \times 0.5) + (0.5\times 3))$

$= 2(15 + 2.5 + 1.5)$

$= 2 \times 19$

$\huge \red \star { TSA = \: 38m {}^{3} }$
