PLs help me find the surface area of the box thxs

290 in^2

Step-by-step explanation:

front side x 2 = 176

top + bottom = 48

sides x 2 = 66

Sum = 290

Total surface areaS_tot = 290 in²  thus c. is your answer

Step-by-step explanation:

lengthl = 8 in

widthw = 3 in

heighth = 11 in

diagonald = 13.9283883 in

total surface areaS_tot = 290 in²

lateral surface areaS_lat = 242 in²

top surface areaS_top = 24 in²

bottom surface areaS_bot = 24 in²

volumeV = 264 in³

Formula and Agenda:

Formulas for a rectangular prism:

Volume of Rectangular Prism:

V = lwh

Surface Area of Rectangular Prism:

S = 2(lw + lh + wh)

l = length

w = width

h = height

d = diagonal

S_tot = total surface area

S_lat = lateral surface area

S_top = top surface area

S_bot = bottom surface area

V = volume

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

multiply each one by 3.14
