The surface area of three adjacent faces of a cuboid are 30cm^2,48cm^2 and 40cm^2 find the voulme of cuboid

a)180 b)240 c)150 d)250


Let the dimensions be l, b, h. We have surface areas of three faces as bh=30, lb=48, hl=40. Multiply these you get (lbh)²=57600. Then volume of cube is going to be lbh=240. Go with option b)
0 0 0
bt the surface area is 2(lb+bh+lh)
That's for the total cuboid, here you just need for one of the two faces. You may verify my answer by reporting it to moderator.
