Question

find the volume,Lsa,tsa and length of a diagonal of a cube each of whose edges measure 6.5cm

Answer 1

Here, side,a = 6.5 cm
  Volume = a³
              = (6.5 cm)³
             = 6.5 cm × 6.5 cm × 6.5 cm
             = 274.625 cm³
  Lateral surface area  = 4a²
                                 = 4 × 6.5 cm × 6.5 cm
                                  = 169 cm²
 Total surface area = 6a²
                             = 6 × 6.5 cm ×6.5 cm
                             = 253.5 cm²
 Diagonal of cube = √3 × a
                           = √3 × 6.5 cm
                           =1.732 × 6.5 cm  ( the value of √3 is taken to as 1.732 )
                           = 11.258 cm
