Answer:
Step-by-step explanation:
Rukhsar painted all except the bottom of the cabinet
Area Painted=
Area Painted Total surface Area of Cabinet - Area of bottom
Total surface area of cabinet
Bottom area of cabinet
Area = Total surface area of cuboid
Area Length x Breadth
- = 2 x 1
- = 2(lb + bh + hl)
- = 2 m²
- = 2(2 x 1 + 1 x 1.5 +1.5 x 2)
- = 2(2 + 1.5 + 3)
- = 2(6.5) = 13 m²
- Thus,
- Area she painted = Total surface area - Bottom area
- = 13-2
- =11 m²

Answer: 11m²
❍ Given :-
The cabinet is a cuboid with measures
- Length (l) = 2m
- Breadth (b) = 1m
- Height (h) = 1.5m
❍ To Find :-
- Surface area cover she painted except the bottom
❍ Solution :-
➸ We know, Rukhsar painted all except the bottom of cabinet.
So,
Area painted = Total surface area of cuboid - Area of bottom

⇝ Total Surface Area of Cabinet
Area = (Total surface area of cuboid)
⇝ Bottom Area of Cabinet
Area = Length × Breadth
Thus,
Area she painted = Total surface area - Bottom area
