Sally has 72 small wooden cubes each measuring 1cm x 1cm x 1cm. she arranged them all so that they form a cuboid. given that the perimeter of the base of the cuboid is 16cm, what is it’s height?

height = 6 cm

Step-by-step explanation:

Sally has 72 small wooden cubes each measuring 1 cm by  1 cm  by 1 cm . The cubes are arranged to form a cuboid. The perimeter of the base of the cuboid is given as 16 cm.

The base of a cuboid is definitely a rectangle and opposite sides of a rectangle is same . since the perimeter is 16 cm, the dimension can be 6 cm by 2 cm. That is 6 + 6 + 2 + 2 = 16 cm. Total cube in the base is 12 cubes.

The

length = 6 cm

width  = 2 cm

height = ?

volume of a cuboid = length × width × height

72 = 6 × 2 × height

72 = 12 × height

divide both sides by 12

72/12  =  height

height = 6 cm

answer:

c) the x-coordinate of the center of the circle increases by 3
