Can someone who is eligible help me with this.?

Step-by-step explanation:

volume of one cube = ½×½×½ = ⅛ cm³

volume of prism = 5×3×6 = 90 cm³

90/(⅛) = 720 cubes to fill the prism.

volume of bottom layer of cubes = 5×3×½ = 7.5 cm³

7.5/(⅛) = 60 cubes on the bottom layer

Each layer is ½ cm in height

6 cm × (1 layer)/(½ cm) = = 12 layers

perimeter = 2×5 + 2×3 = 16 cm

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
