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:
x ≈ - 6.74, 0.74
Step-by-step explanation:
x² + 6x - 5 = 0 ( add 5 to both sides )
x² + 6x = 5
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 5 + 9
(x + 3)² = 14 ( take square root of both sides )
x + 3 = ±
( subtract 3 from both sides )
x = - 3 ± 
Then
x = - 3 -
≈ - 6.74 ( to the nearest hundredth )
x = - 3 +
≈ 0.74 ( to the nearest hundredth )
