The total surface area required in each case is:
5) 25.92 m²
6) 300.56 m²
7) 846 in²
8) 600 in²
What is the total surface area of the rectangular prism?
Formula for the total surface area of a rectangular prism is:
TSA = 2(lw + lh + wh)
where:
l is length
w is width
h is height
5) TSA = 2((1.8 * 1.8) + (1.8 * 2.7) + (1.8 * 2.7))
TSA = 25.92 m²
6) TSA = 2((9.4 * 6.3) + (9.4 * 5.8) + (5.8 * 6.3))
TSA = 300.56 m²
7) TSA = 2((12 * 15) + (9 * 15) + (12 * 9))
TSA = 846 in²
8) TSA = 6(10 * 10)
TSA = 600 in²
