Answer:
1). Option (d)
2). Option (c)
3). Double the height
Step-by-step explanation:
1). If we triple the length of a box of milk dude,
New length of the box will become 3 times the previous length.
Option (d) is correct.
2). Surface area of box 'S' = 2(lb + bh + hl)
Where l = length of the box
b = Width of the box
h = height of the box
If all of these dimensions are tripled,
Surface area of the box = 2[(3l)(3b) + (3b)(3h) + (3h)(3l)]
= 2(9)[lb + bh + hl]
= 9S
Therefore, 9 times material will be required.
Option (c) is correct
3). From the picture attached,
Width of the box is less than the height of the box.
Volume of a rectangular box = lbh
If we double the length of the given box, volume of the box will be more than doubling the width of the box.
In simpler words, more space to put the candies will be created if we double the length of the box.
