Johanna carves a square block of wood that has on one side an area of 872 square inches. To the nearest integer, what is the length of the side?
A. 30
B. 28
C. 26
D. 24
Is the answer A?
Thank you
well, 30 would be 900
and 28 would be 784
so do my proportion thing again
28 x 30
784 872 900
(872 -784)/ (x-28) = (900-784)/(30-28)
x-28 = 2*88/116
x = 28 + about 1.5
or around 29.5
so
30
try calculator
sqrt (872) = 29.529
yes the answer is A
To find the length of the side of the square block, we need to find the square root of the area. In this case, the area is given as 872 square inches.
To find the square root, you can use a calculator or perform an approximate calculation. In this case, we will use a calculator.
Taking the square root of 872 gives us approximately 29.52. Since we need to round to the nearest integer, the length of the side is approximately 30 inches.
Therefore, the answer to the question is not A. The correct answer is rounded to the nearest integer, which is 30.
