Step-by-step explanation:
Answer: 1.574 × 10-3
Step-by-step explanation:
To convert 0.001574 into scientific notation, follow these steps:
Move the decimal 3 times to right in the number so that the resulting number, m = 1.574, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -3
Write in the scientific notation form, m × 10n
= 1.574 × 10-3
If we have triangular pyramid with a side of s and all the faces and the base are equilateral triangles, then the formula for the total surface area is
SA = 3As + Ab
Where As is the area of the three faces
and
Ab is the area of the base
Since the triangles are equilateral, the surface area in terms of s is
SA = 3 (√3/ 4) s² + √3/ 4 s²
SA = √3 s²
