Answer:

<em>514 square meters</em>

Step-by-step explanation:

Consider the length of p;

11 * p * 3 = 528,\\33 * p = 528,\\p = 528 / 33 = 16 meters

11, 3, and p act as the length, width, and height of this rectangular prism. We can apply the volume formula length * width * height, and thus made 11 * p * 3 equivalent to the volume 528. Now let us determine the surface area;

Area of Side 1 = 16 * 11 = 176 square meters,\\Area of Side 2 = 3 * 16 = 48 square meters,\\Area of Side 3 = 11 * 3 = 33 square meters,\\\\Surface Area = 2 * ( 176 ) + 2 * ( 48 ) + 2 * ( 33 ) = 352 + 96 + 66 = 514 square meters

<em>Hope that helps!</em>

You have a set of cards labeled 1-10. Set A is drawing an even card. Set B is drawing a 8 or higher.  What is the  P ( A ∪ B ) ?
creativ13 [48]

set A = {2, 4, 6, 8, 10}   (only even cards)

set B = {8, 9, 10}    (8 or higher)

( A ∩ B ) means the numbers which are common in both sets .

They both have 8 & 10 in common. 

So the answer is: P(A ∩ B) = {8,10}
