Question

Find the surface area of the prism below. Please see attachment and the answer C. 1200cm^2 is incorrect. Thanks!

Answer 1

Answer: option a

Explanation:

You must apply the formula for calculate the surface area of the prism, which is shown below:

`SA=bh+2ls+lb`

Where:

b=8 cm

h=3 cm

l=10 cm

s=5 cm

When you susbstitute the values shown above into the formula for calculate the surface area, therefore you obtain:

`SA=(8cm*3cm)+2(10cm*5cm)+(10cm*8cm)\\SA=204cm^(2)`
