Just take the 13, then add 8, then subtract 4, then with what you got keep going on to the next term.
8.5, since there are 2 significant digits, the only 2 numbers would be 8 and 4, so round at 4 since 5 isn't included by is above and equal to 5
Get the value of the decimal:

Remember that percentages are simply the value of a decimal multiplied by 100. (From the Latin, "per centus", meaning "per 100")
therefore:
The surface area of the triangular pyramid shown is 94.6 in²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The surface area of the regular pyramid is given as:
Surface area = 3(0.5 * 4.3 * 13) + (0.5 * 4.3 * 5) = 94.6 in²
The surface area of the triangular pyramid shown is 94.6 in²
