Find the surface area and the volume of a rectangular solid measuring 5 m by 4 m by 3 m. Also find the length of a diagonal.

In a rectangular solid, Let l = 5 m, b = 4 m and h = 3 m By formula, Surface area of rectangular solid = 2(lb + bh + lh) = 2(5 × 4 + 4 × 3 + 5 × 3) = 2(20 + 12 + 15) = 2 × 47 = 94 m 2 Volume of rectangular solid = l × b × h = 5 × 4 × 3 = 60 m 3 . Diagonal of cuboid = Hence, surface area = 94 m 2 , volume = 60 m 3 and the length of diagonal is 7.07 m.
