The answer is 988 square inches. L=23 W=10 H=8
The equation for surface area is 2(L x W) + 2(L x H) + 2(W x H)
Next, you need to substitute the values into the equation to get:
Surface area= 2(23 x 10) + 2(23 x 8) + 2(10 x 8)
Now finish solving the equation to get an answer of 988 square inches!
You can solve this problem by using the Gauss method. The Gauss method is a method where you can add the first and last numbers together, and then multiply by how many times that appears. Here, the sum of the first and last number is -11. In this sequence, it would appear ten times (since there are ten terms and the terms are used twice in every eleven). -11 * 5 is -55, so that means the answer to this question is -55.
Answer:
Answer: 1/12
Step-by-step explanation:
2/5x-4=8-3/5x.
We want to tank x out of the denominator by multiplying x on both sides.
2/5-4x=8x-3/5
Now we simplify
-12x=-1
x=1/12
Put x in the equation to check it
