The ratio between the LSA and area of base of a cuboid is ……A) \(2

1.	The ratio between the LSA and area of base of a cuboid is ……A) \(2(l-b)\,h:lb\)B) \((l+b)\,h:lb\)C) \(2(l+b)\,h:lb\)D) \(2(l+b)\,:lb\)
Answer» Correct option is (C) \(2(l+b)\,h:lb\) L.S.A. of cuboid \(=2(l+b)\,h\) Area of base of cuboid \(=lb\) \(\therefore\) Required ratio \(=\frac{2(l+b)\,h}{lb}\) \(=2(l+b)\,h:lb\) Correct option is C) \(2(l+b)\,h:lb\)

The ratio between the LSA and area of base of a cuboid is ……A) \(2(l-b)\,h:lb\)B) \((l+b)\,h:lb\)C) \(2(l+b)\,h:lb\)D) \(2(l+b)\,:lb\)

Answer»

Correct option is (C) \(2(l+b)\,h:lb\)

L.S.A. of cuboid \(=2(l+b)\,h\)

Area of base of cuboid \(=lb\)

\(\therefore\) Required ratio \(=\frac{2(l+b)\,h}{lb}\)

\(=2(l+b)\,h:lb\)

Correct option is C) \(2(l+b)\,h:lb\)
