Answer:

1. h = 3 inches

2. a) 27 cubes b) 1/27 cubic inches

Explanation:

1:

Area of a triangle is A = (1/2)bh (base x height)

5 1/10 = (1/2)(3 2/5)h

Now just solve for h.

Divide both sides by 1/2 to get rid of the 1/2

10 1/5 = (3 2/5)h

Divide both sides by 3 2/5

h = 3

2:

a) 3 cubes are needed to get one edge length of 1 inch.

3 x 3 x 3 = 27 cubes

b) Volume of a cube is just V = s^3

V = (1/3)^3 = 1/27 cubic inches
