The surface area of this rectangular solid is? (it does contain a top)

444 inches2

560 inches2

332 inches2

560 inches3

Step-by-step explanation:

surface area=2(l+w)×h+2×l×w

=2(14+5)×8+2×14×5

=2×19×8+140

=304+140

=444 inches²

Step-by-step explanation:

Side 1 = a

Side 2 = b

Side 3 = c

a = 2b

c = 5ft. + b

a + b + c = 49 feet

Substitute

2b + b + 5ft + b = 49 ft

Add the b’s

4b + 5ft = 49ft

Subtract 5ft from both sides of the equation

4b = 44ft

Divide both sides of the equation by 4 to isolate b

b = 11ft

a = b * 2 = 11 * 2 = 22ft

c = 49ft - 11ft - 22ft = 16ft

Hope this helps :)
