Abox has rectangular top, bottom, and sides. the top and bottom are square. the volume must be 7 cubic meters. express the total surface area a of the box in terms of the height h (in meters) of the box.

Step-by-step explanation:

Given

Box has top and bottom as  square

let l ,b ,h be length, breadth and height of box

l=b because top and bottom as square

thus

Total surface area

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
