Find find the surface area of a rectangle or pyramid with these measurements: L equals 8CMW equals 4CMNH equals two CM express your answer as a decimal rounded to the nearest hundredth
To find the surface area of a rectangle or pyramid, we need to know whether we are dealing with a rectangle or a pyramid. The formula for the surface area of a rectangle is given by:
Surface Area = 2lw + 2lh + 2wh
Where:
l = length
w = width
h = height
Based on the given measurements, we have l = 8 cm, w = 4 cm, and h = 2 cm.
So, the surface area of the rectangle can be calculated as:
Surface Area = 2(8 cm)(4 cm) + 2(8 cm)(2 cm) + 2(4 cm)(2 cm)
Surface Area = 64 cm² + 32 cm² + 16 cm²
Surface Area = 112 cm²
Therefore, the surface area of the rectangle is 112 cm².
