Answer:
Amanda needs 24grams more of paint to paint the unpainted surfaces
Step-by-step explanation:
A cube contains 6 surfaces
Let the wooden cube(painted) have a side length of 2 units.
Therefore,
Area of the wooden cube(painted) = 2 x 2 x 6
=24grams
The wooden cube is cut into 8 Equal cubes
The side length of the smaller cube is 1
Area of each small cube= 1 × 1 × 6 =6
Area of total small cube=6×8
=48grams
Unpainted area=Total area of small cubes - total painted area
=48g-24g
=24grams
Amanda needs 24grams more of paint to paint the unpainted surfaces
