Answer:
248 in²
Step-by-step explanation:
Given the net of the rectangular prism above, to find its surface area, find the length and width of each part of the net, calculate the area of each and add all the areas together.
==>Measurement and areas of each part of the net (note: each small box = 2 in):
There are 6 parts of the net
=>Area of 2 parts:
2 of the parts of the net have the same measurement, L = 6 in, W = 4 in
Area of 2 parts = 2(6*4) = 2(24) = 48 in²
=>Area of 2 parts:
Measurement: L = 10 in, W = 4 in
Area = 2(10*4) = 2(40) = 80 in²
=>Area of 2 parts:
Measurement: L = 10, W = 6
Area = 2(10*6) = 2(60) = 120 in²
Surface area of the prism = 48+80+120 = 248 in²
