Question

Find the volume , total surface area , lateral surface area and lengty of diqgonal of a cube whose side is 2cm6mm

Answer 1

Length of edge of cube (a) = 2 cm 6 mm = 2 cm + 0.6 cm = 2.6 cm

Now,

Total Surface Area = 6*a² = 6*2.6*2.6 = 40.56 cm²

Lateral Surface Area = 4*a² = 4*2.6*2.6 = 27.04 cm²

Length of Diagonal = √3a² = a√3 = 2.6 * 1.732 = 4.5032 cm
