volume of cube = volume of cuboid
a³ = l*b*h
a³ = 100*80*64
a = ∛512000
a = 80cm
surface area of cube
6a²
6*80*80
38400cm²
a³ = l*b*h

Step-by-step explanation:
volume of cuboid = l*b*h
= 200 × 80 × 64
= 5 12000
volume of cube = volume of cuboid
side*3 = ³√512000
side = 80 cm
surface area of cube = 6 side*2
= 6 × 80 x 80
= 38 400 cm*2
