Answer:
a³ + 18
Explanation:
The formula for cube volume is to cube the side meaning multiply the side by itself 3 times. Adding 18 could just be the other side, so this method would be the most correct.
I got 404 I think that is right but I am not sure to check me figure out the rectangles that have no information by using the information you have but to figure out the middle pat add all the lengths together and m multiplyit by 8
Answer:
11.108
Step-by-step explanation:
Alright, so you know that the formula for the area of a triangle is a=bh/2
First start out by identifying your base and height.
Base is the side that the shape is "standing on", in this case, that would be 9cm.
Now, the height is the measurement that is perpendicular (90 degrees to the base), which in this case is 12 cm.
Now, plug these values into your formula
(12)(9) /2 = 54 cm squared! hope this helps :)
