Find how many cubes of side 1 cm each can be made by melting a cuboid with dimensions 20cm × 40cm × 5cm?
Volume of cuboid = 20x 40x 5 ; Volume of cube = 1x 1x 1 , Hence number of cubes = volume of cuboid/volume of cube = (20 x 40 x 5)/(1 x 1 x 1) = 4000
√529 + √64 + 92 = ?
60% of 250 + 14 × 10 - 210 = ?
135÷ 15 x 19 + 14807 = ? + √3249 - √9604
Solve the following:
523 + 523 x 523 ÷ 523
(0.064 × 3.2 × 2.5) ÷ (0.0016 × 4 × 1.25) = ?2 – 57
√(24²+285-8²-172) = ?²
125 + 64% of 250 = 150 + ?
13/3 – (23/6) = ? – (22/9)
?% of 120 × 3√343 = 42 × 20
166/? = √576 - 3.25
