The height of the bread is 5 cm.
Surface Area
The surface area of bread is the total sum of the area of base and perimeter. The surface area of the bread is given below.
[tex]A = 2 \times b + p \times h[/tex]
Where
, b is the area of the base, p is the perimeter of the base and h is the height.
Given that 50% of the surface area of the bread is the crust. It means that the surface area of both sides of the base is equivalent to the surface area of its perimeter.
[tex]2\times b = p\times h[/tex]
The perimeter of the bread is given below.
[tex]p = 4 \times length[/tex]
[tex]p = 4\times 10[/tex]
[tex]p = 40\;\rm cm[/tex]
The area of the base is given below.
[tex]b= 10\times 10[/tex]
[tex]b = 100 \;\rm {cm}^2[/tex]
Substituting the values in the above formula,
[tex]2\times 100 = 40 \times h[/tex]
[tex]h=5 \;\rm cm[/tex]
Thus the height of the bread is 5 cm.
