Answer:
The area of the triangle is .
Step-by-step explanation:
The area <em>A</em> of a triangle is given by the formula where <em>b</em> is the base and <em>h</em> is the height of the triangle.
From the graph, we can see that the base is 3 units and the height is 4 units. Therefore, the area of the triangle is
Given:
The value of the solid's surface area is equal to the value of the solid's volume.
Length(l) = 9 units
width(b) = 4 units
Height(h) = x units
To find:
The value of x.
Solution:
Solid's surface area is
Volume of solid is
Solid's surface area = Volume of solid
Divide both sides by 10.
Therefore, the value of x is 7.2.
