Question

the surface area of a cuboib 12m long 8m broad and 5m hight is​

Answer 1

Answer:

392 metersquare

Step-by-step explanation:

Given :

L= 12m

B= 8m

H= 5m

As we know that Surface area of cuboid is..

2(LB+BH+LH)

area of cuboid =

2(12*8+8*5+12*5)

=392

Answer 2

ANSWER:

• Surface area of Cuboid = 392cm²

GIVEN:

• Length = 12m
• Breadth = 8 m
• Height = 5 m

TO FIND:

• Surface area of Cuboid.

SOLUTION:

Formula:

Surface area of Cuboid = 2(lb+bh+lh)

= 2(12*8+8*5+12*5)

= 2(96+40+60)

= 2(196)

= 392 m²

NOTE:

some important formulas

• Volume of Cuboid = (length)(Breadth)(Height)
• Volume of cube = (Edge)³
• Volume of cylinder=πr²h
• Curved surface area of Cylinder = 2πrh
• Total surface area of Cuboid = 2(lb+bh+lh)
• Curved surface area of Cuboid = 2(l+b)h

Where:

• l = lenghth
• b = breadth
• h = height
• r = radius
• h = height
