Volume of the rectangular solid = \(length * width * Height\)

or\(24 = Length * 4 * Height\)

or \(Length * Height = 6\)

Since it is given all sides are less than 6 and are integer

so we can take Length = 3 and Height = 2 or vice-versa as it will end up the same result

Now Surface Area of the rectangular solid =\(2 * ( Length * width) + 2 * (Width * Height) + 2 * (Length * Height) = 2 * ( 12 + 8 + 6) = 52\)
