Answer:
The surface area of Rectangular prism is .
Step-by-step explanation:
Given:
Length of the rectangular prism = 7 cm
Width of the rectangular prism = 5 cm
Height of the rectangular prism = 12 cm
we need to find the surface area of rectangular prism.
Solution:
the surface area of rectangular prism is equal to 2 times sum of length times width and width times height and length times height.
framing in equation form we get;
the surface area of rectangular prism =
the surface area of rectangular prism =
Hence The surface area of Rectangular prism is .

Answer:
52
Step-by-step explanation:
Given that :
Mean (m) = 78
Standard deviation (s) = 13
Score that is 2 standard deviations below the mean
Using the relation :
Zscore = (x - m) / s
2 standard deviations below the mean means a Zscore of - 2
Hence,
-2 = (x - 78) / 13
Cross multiply
-2 * 13 = x - 78
-26 = x - 78
x = - 26 + 78
x = 52
Score which is 2 standard deviations below the mean is 52
