Question

find the total surface area of cuboid whose Length breadth and height are 8 cm 7 cm and 4 cm respectively

Answer 1

Lenght=8cm
Breadth=7cm
Height = 4cm
T.S.A of cuboid=2(lb+bh+lh)
= 2(8*7+7*4+8*4)
= 2(56+28+32)
= 2(116)=232cm.^2
So Total surface area of this cuboid is 232cm^2

Answer 2

Answer:

=> 232$cm^2$

Step-by-step explanation:

As per the data given in the question, we have to find the total surface area of the cuboid.

Given that:-

The length of a cuboid (l) $=8cm$

The breadth of a cuboid (b) $=7cm$

The height of a cuboid (h) $=4cm$

As we all know, the formula for the total surface area of a cuboid

$=>2(lb+bh+hl)$  

$=>2(8\times7+7\times 4+4\times 8)$

Multiply the numbers, we get

$=>2(56+28+32)$

Now, adding the terms in the brackets,

$=>2(116)$

Multiply the numbers,

$=>232cm^2$

Hence, the total surface area of a cuboid 232$cm^2$
