The answer for number 17
1 answer:
Since cube has all faces as Squares
perimeter of each face P = 22.2
as we know perimeter of a square is P = 4 * ( Sides of a square )
let the sides of the square be 'x'
Hence , 22.2 = 4 * x
=> x = 22.2/4
=> x = 5.55
hence the edge's length is 5.55
Note : if the length from edge to edge is asked then
Length of the Diagonal for a cube =
Hence we get edge to edge length as
√3 * 5.55 = 9.612

Answer: Option b.
Step-by-step explanation:
First, you need to calculate the ratio of the area. This is:
You know that the area of the smaller trapezoid is 771 m², then you can set up the following proportion, where "x" is the area of the larger trapezoid. Then you have:
Now you must solve for "x". Therefore, you get that the area of the larger trapezoid is:
