Question 4:-
Meghna painted the outside of the
cabinet of measure
2m*3m*2.5m. How much surface area did she cover if she painted
all except the bottom of the cabinet and back side ?​

Answer 1

Answer:

Lenth = 2m

Breadth = 3m

Height = 2.5m

Since bottom and backside isn't painted...

This is a case of Curves Surface Area

CSA = 2(l+b)h

= 2(2+3)2.5

= 2 × 5 × 2.5

= 25m^2

Answer 2

The area she painted is 23.5 sq. m.

Step-by-step explanation:

Since we have given that

Length = 2 m

Width = 3 m

Height = 2.5 m

So, we need to paint it except the bottom and back side.

So, Surface area would be

$lb+bh+2lb\\\\=2\times 3+3\times 2.5+2\times 2.5\times 2\\\\=6+7.5+10\\\\=23.5\ m^2$

Hence, the area she painted is 23.5 sq. m.
