Question

Pramila paint in the outer surface of a cabinet of measures 1 m into 2 metre into 1.5 m find the surface area she cover if she painted all except the bottom of the cabinet

Answer 1

Answer:

15 metre

Step-by-step explanation:

The answer is really easy I can explain it to you

L=1m B=2m and H=1.5m

Formula of TSA(Total Surface Area) of a Cuboid is: 2(lb + bh + lh)

So 2(1x2 + 2x1.5 + 1x1.5)

2(2 + 3 + 1.5)

2 X 6.5

13

Wait we also had to paint the upper part so it's area would be L x B

Which means 1m x 2m=2m

13 + 2 = 15m

Answer 2

Step-by-step explanation:

Answer :

Length (l) of the cabinet = 2 m

Breadth (b) of the cabinet = 1 m

Height (h) of the cabinet = 1.5 m

Area of the cabinet that was painted = 2h (l + b) + lb

= [2 x 1.5 x (2 + 1) + (2) (1)] m2

= [3(3) + 2] m2

= (9 + 2) m2

= 11 m2
