Question

if x equals 2 units y equals 11 units and Z equals 6 units and what is the surface area of the rectangular prism

Answer 1

We will determine the surface area of the solid as follows:

*First: We can see that the solid is composed of three pairs of sides, so we will have to calculate the area of just 3 different faces.

*Second: We determine the areas:

$A_1=x\cdot y\Rightarrow A_1=2\cdot11\Rightarrow A_1=22$$A_2=x\cdot z\Rightarrow A_2=2\cdot6\Rightarrow A_2=12$$A_3=y\cdot z\Rightarrow A_3=11\cdot6\Rightarrow A_3=66$

*Third: We add the areas to determine the surface area:

$S_A=2(A_1+A_2+A_3)\Rightarrow S_A=2(22+12+66)$$\Rightarrow S_A=200$

So, the surface area is 200 square units. [Option C
