Question

A wood cubical box costs ₹3840 at ₹250 per metre square.find the volume and length of each side of the box.

Answer 1

Answer:

Total cost = ₹3840

Cost per meter = ₹250

∴ Area of cubical box = 3840/250 = 15.36m²

TSA = 6a²

6a² = 15.36

a²   = 15.36÷6

a² = 2.56

a   =  √2.56

Side = 1.6m

Volume = a³

             = 1.6×1.6×1.6

             = 4.1m²
