Hi, from the question given that a cuboid has volume 120 cm3.
00:09
So volume of cuboid is 120 cm3 and the area of base of the cuboid is 30 cm2.
00:33
So let us consider a cuboid.
00:46
So here it is given that volume is 120 cm3 and the base, so this is the base part.
00:56
So area of the base of the cuboid is 30.
01:00
So base is nothing but the rectangle.
01:03
So in general we know that volume of cuboid is length into breadth into height and area of rectangle since the base is in the shape of rectangle will be length into breadth.
01:27
So here volume is given as 120 which is equal to lbh and the area lb is equal to 30.
01:38
So here we need to find the surface area of the cuboid.
01:41
So surface area of the cuboid is 2 times of lb plus bh plus lh.
01:50
So by using this we need to find the dimension of the given cuboid.
01:55
So first substitute lb is equal to 30 here...
