Apiece of sheet metal is cut and bent to form a box, as shown. the box has no top. find the area of

a. the bottom: sq. cm

b. the two longer sides: sq. cm

c. the two shorter sides: sq. cm

a) 72 cm²

b) 72 cm²

c) 8 cm²

Step-by-step explanation:

Given :   A piece of sheet metal is cut and bent to form a box, as shown. The box has no top.    

Length of box = 18 cm

Breadth of box = 4 cm

Height of box = 2 cm

Area of rectangle = Length × Breadth

a) To find the area of  the bottom

Since, base of box has dimension 18 cm and 4 cm

So, area of base =  18 × 4 = 72 cm²

b) To find the area of  the two longer sides

longer side is side with  length 18 cm and breadth 4 cm

So area of side with longer side = 18 × 4 = 72 cm²

Thus, the area of two longer side is same as area of base = 72 cm²

c)To find the area of  the two shorter sides.

shorter side is side with breadth  4 cm and height 2 cm

So area of side with shorter side = 4 × 2 = 8 cm²

Thus, the area of  the two shorter sides  is 8 cm².

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
