# Find the Volume and the Total Surface Area of a Cuboid, Whose : L = 3.5 M, B = 2.6 M and H = 90 Cm - Mathematics

Sum

Find the volume and the total surface area of a cuboid, whose :

l = 3.5 m, b = 2.6 m and h = 90 cm

#### Solution

Length = 3.5 m Breadth = 2.6 m, Height = 90 cm = 90/100 m = 0.9 m.
Volume of a cuboid = l x b x h = 3.5 x 2.6 x 0.9 = 8.19 m3
Total surface area of a cuboid = 2(l x b + b x h + h x l)
= 2 (3.5 x 2.6 + 2.6 x 0.9 + 0.9 x 3.5) = 2 (910 + 2.34 + 3.15) = 2(14.59)= 29.18 m2
