What is the surface area of a prism that has a height of 4cm, a length of 5cm, and a width of 10cm.
1 answer:
Answer: 220 cm squared
Step-by-step explanation: Formula for surface area of a prism...
S = 2(lw + lh + wh) l = 5 w = 10 h = 4
so
lw is 5 x 10 = 50
lh is 5 x 4 = 20
wh is 10 x 4 = 40
plug these into equation...
S = 2(50 + 20 + 40)
S = 2(110)
S = 220
