Answer:
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

Answer:
65 girls
Step-by-step explanation:
325/25=13 13x5=65
We know that
area of triangle=b*h/2
b=(x-2) m
Area=(x²-4) m²
h=?
(x²-4)=(x+2)*h/2
but remember that
(x²-4)=(x+2)*(x-2)
so
subsititute
(x+2)*(x-2)=(x+2)*h/2
(x-2)=h/2
h=2*(x-2)
the answer is
<span>the height of a triangle is 2*(x-2)</span>
Here you go, hope this helps!
