The three co-terminous edges of a cuboid are36, 75 and 80 cm respectively. The edge of thecube of the same volume will be:(a) 60 cm(c) 50 cm(b) 55 cm(d) 65 cm |
|
Answer» Given the dimensions of cuboid: Length = 36 Breadth = 75 & Height = 80 We know that the volume of a cuboid = L * B * H Therefore the volume of the given cuboid = 36 * 75 * 80 ⇒ Volume = 216000 Also, it is given that this volume is same for the cube as well. Therefore the volume of cube is equal to a³, where a = side of the cube ⇒ volume of the cube = a³ = 216000 Taking cube root on both sides ⇒ a = 60 Therefore the side of a cube is 60. |

The product of two numbers is 1575 and their quotient is . Find the numbers.(A) 21, 7536B)35, 45(C) 63, 25(D) 105, 15 |
|
Answer» So x*y = 1575 and x/y = 9/7 So x = 9y/7 and thus (9y/7)*y = 1575 ---> y^2 = (7/9)*1575 = 1225 ---> y = +/- 35. If y = 35, then x = 1575/35 = 45 If y = -35, then x = -45. So there are two solution sets, namely {45, 35} and {-45, -35) I want it with single variable |
