Answer:
The surface area is
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to
where
b is the length side of the square base
h is the height of the lateral triangular face
we have
Applying Pythagoras Theorem find the value of h
substitute in the formula
Simple way of finding the decimal value : -
=> 46/200
Divide numerator and denominator by 2
=23/100
As 100 is in denominator, shift decimal by 2, i.e
= 0.23
Answer = 0.23
The result is
3x^2 + 2 + 3/2x-1
Answer:
2.3333
Step-by-step explanation:
The area of the counter top is 16 ft by 3 ft so 16 x 3= 48. The area of the counter top is 48 ft squared.Then you have to convert it to meters squared, 48 x 0.092903 = 4.459244. Then multiply that by 28 to get your answer.4.459244 x 28 = 124.861632. The total cost is about $124.86
