Help please with surface area
I know the answer I just need help showing my work
Picture below

Step-by-step explanation:

you have to find the area of each side

for the two triangles(front and back sides) A=BH/2 so 45 but since there are two triangles you multiple by 2 so 90

For two rectangular sides(the ones on the sides) A=LW so 144.2 but there are two so 288.4

For the bottom rectangle A=LW so 140

Then add them together

90+288.4+140= 518.4

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
