SA=2(lw+wh+lh) This is the formula for finding the surface area of a rectangular prism, where SA is surface area, l is length, w is width, and h is height.
208=2(lw+wh+lh) 104=lw+wh+lh Here, I divided both sides by 2 to get ride of the 2.
Now, I used prime factorization to find out all the prime factors of 104, which are 2, 2, 2, and 13. Since rectangular prisms only have 3 dimensions, I needed to combine two of the prime factors. In this case, I can either combine 2 of the 2s to get 2, 4, and 13 or I can combine 13 with one of the 2s to get 26, 2, and 2.
If my dimensions were 2, 4, and 13... my surface area would be 172 sq cm.
If my dimensions were 2, 2, and 26... my surface area would be 208 sq cm.
Hence, the width of the rectangular prism when the surface area is 208 square centimeters can be either 2 or 26.
The government will give the same amount of available social security number to each state. So the available social security number pool will be divided by the total number of states. There are a total of 50 states in the USA. If the number pool is 5 x 10^9, then each state going to have:
5 x 10^9 /50= 0.1 * 10^9 = 1*10^8
The answer will be D since 1 x 10^8 and 100,000,000 is the same number
Annual interest is P*r^t, r is 0.05 here, t is 9/12=3/4=0.75 P*0.05^0.75=120 use your calculaor: P= 120÷ (0.05)^0.75=1135 so he invested about 1135 dollars <span><span><span><span>
