Question

Find the surface area of a cuboid of
dimensions 3.8 cm, 3.4 cm and 6.2 cm.​

Answer 1

Answer:

1382.4

Step-by-step explanation:

TOTAL SURFACE AREA OF CUBOID = 2 X (LB+LH+HB)

= 2X(3.8 x 3.4 + 3.8 x 6.2 + 6.2 x 3.4)

= 2 x (57.56)

= 115.12

Answer 2

Answer:

115.12

Step-by-step explanation:

Given

length of cuboid=3.8cm

Breadth=3.4cm

Height=6.2cm

Solve=

surface area of a cuboid =

$2(lb + bh + hl)$

$2(3.8 \times3.4 + 3.4 \times 6.2 + 3.8 \times 6.2)$

$2(12.92 + 21.08 + 23.56)$

$2(57.56)$

$115.12$

So,Surface area of cuboid=115.2
