The answer must be

since the triangular pyramid has 4 faces and each has an area of 30

we should multiply that by 4 , so :
Y = 18( 0.58) ^t
It would be written as :
Y = 18(0.11) ^ (t/4)
Y = 18 (0.11 ^ (1/4)) ^ t
But
0.11 ^ (1/4) = 0.5759
Plug the value
Y = 18 (0.5759) ^ t
Two decimal point :
Y = 18 (0.58) ^ t
<h3>Yes, this is true.</h3>
To be considered similar triangles, the angles must be the exact same, and the sides must be proportional. The side lengths do not have to be exactly the same, but they must be proportional (like a ratio, suppose one triangle has a side length of 1, and the similar triangle has a side length of 3. The ratio is 1:3, and all sides will follow this ratio.)
