You can put this solution on YOUR website!
let L,W,H be the dimensions of the box then volume= L x W x H=LWH now if we each of the dimension is quadruppled new dimension will be 4L,4W,4H so volume will be V=4L x 4W x 4H=64LWH so volume is increased by 64 times the original volume.
similarly surface area = 2(LW+LH+WH)
new surface area = 2(16LW+16LH+16HW)
=32(LW+LH+HW) surface area increased by 32 times
