Solution: Top = LxW 10m

x 5m= 50m

To find the (TSA) you have times length x width of each side , then add it up all together times 2. Ex: TSA=2(T+F+S)

TSA= 2( T+F+S)

TSA= 2( 50 + 60 + 30)

TSA= 2(140)

TSA= 280m

Front= LxW 6m x 1om= 60m

Side= LxW 6m x 5m = 30m

Total Surface Area: (TSA)

Side= LxW 6m x 5m = 30m

Total Surface Area: (TSA)

To find the (TSA) you have times length x width of each side , then add it up all together times 2. Ex: TSA=2(T+F+S)

TSA= 2( T+F+S)

TSA= 2( 50 + 60 + 30)

TSA= 2(140)

TSA= 280m
