Surface area = 56 cm2
Explanation:
Area of square base = Side x Side = 4 x 4 = 16 cm2
Area of triangle = 1/2 x Base x Height = 1/2 x 4 x 5 = 10 cm2
Area of 4 triangles = 10 x 4 = 40 cm2
Surface area of pyramid = 16 + 40 = 56 cm2
Answer:
645
Step-by-step explanation:
Let's first try and write our series up to 125 before we know the next number.
Well continue from the given series.
0, 1, 1, 3, 6, 9, 27
The next number= 27+4= 31 , then 31 *4 = 124
The next after 124 = 124+5= 129, then 129*5 = 645
So actually the question was supposed to be the term greater than 124 because 125 does not exist in the series.
The number is 645
