Question

The total surface area of cuboid is 600sqcm. It length is 6 and breath is 7 . Find its height and volume of cuboid?​

Answer 1

Step-by-step explanation:

formula to find the T.S.A of cuboid = 600 cm²

2(lb+bh+hl) = 600 cm²

2(6×7+7×h+h×6) = 600cm²

6×7+7×h+h×6 = 600/2 = 300cm

42+7h+6h = 300

13h = 300 -42

13h = 258cm²

h = 258/13

h = 19cm
