If `l xx b xx h=20 xx 12 xx 10`, then find the volume of cuboid.

A student follows the rule 3 xx 3 + 3 xx 3 = 12 , 4 xx 4 + 4 xx 4 = 16, 5 xx 5 + 5 xx 5 = 20, then find the value of the expression 12 xx 12 + 12 xx 12 according to this rule.

A student follows the rule 3 xx 3 + 3 xx 3 = 12, 4 xx 4 + 4 xx 4 = 16 , 5 xx 5 + 5 xx 5 = 20 , then find the value of the expression 12 xx 12 + 12 xx 12 according to this rule.

If 12xx16=188 , and 14xx18=248 , then find the value of 16xx20=?

The dimensions of a cuboid in cm are 10 xx 9 xx 5. The volume of the cuboid is

The volume of a cuboid is given by the product of its length, breadth and height. The length of a cuboid is 2x^2 times its breadth and the height is 3/2x y\ times of length. Find the volume of the cuboid if its breadth is 6y^2

The length, breadth and height of a cuboid are in the ratio 1:2:3. The length, breadth and height of the cuboid are increased by 100%, 200% and 300% respectively. Then the increase in the volume of the cuboid is (a) 5 times (b) 6 times (c) 12 times (d) 17 times

(i) Find the value of 1.238 xx 10 . (ii) Find the value of 1.31 xx 1.2 .
