Question
Rohan had a cuboidal box having dimensions of 36 cm ×
25 cm × 20 cm. He packed into it as many cubes as possible, each of which has edges 4 cm long. How much space will be still left in the box?Solution
Volume of the cuboidal = (36 × 25 × 20) cm³ Maximum volume of the cubes which can fit into the box. (36 x 24 × 20) cm³ (24 cm because that is the max dimension of 4 cm that can cover for space of 25 cm) of the cube. Now, the space left (36 x 25 x 20) - (36 × 24 × 20) 18000-17280 = 720 cm3 720 cm³ space will be still left in the box.
(500 × 6 ÷ 10) - (√256 + 8) = ?
22% of 400 + √ ? = 34% of 800 - 25% of 400
(2/5)(32% of 4500 – 440) = ? × 8
1550 ÷ 62 + 54.6 x 36 = (? x 10) + (28.5 x 40)
What will come in the place of question mark (?) in the given expression?
96 ÷ (9 - 6.6) + 17.5 X 6 = ? ÷ 8
13 X ? = 85 X 4 + √81 + 2
45% of 360 - 160 + ? = √324
((67)32 × (67)-18 / ? = (67)⁸
4567.89 - 567.89 - 678.89 = ?
82.3 × 644.7 × 723.4 × 815.85 = 72?
