help please? even if someone gave me the steps to figure the answer myself, that'd be great​

Answer:The height is 28.57 cm.The surface area is 9,628 cm^2.Step-by-step explanation:I assume the cooler is shaped like a rectangular prism with length and width of the base given, and with an unknown height.volume = length * width * heightFirst, we convert the volume from liters to cubic centimeters.60 liters * 1000 mL/L * 1 cm^3/mL = 60,000 cm^3Now we substitute every dimension we have in the formula and solve for height, h.60,000 cm^3 = 60 cm * 35 cm * h60,000 cm^3 = 2,100 cm^2 * hh = (60,000 cm^3)/(2,100 cm^2)h = 28.57 cmThe height is 28.57 cm.Now we calculate the internal surface area.total surface area = area of the bases + area of the 4 sidesSA = 2 * 60 cm * 35 cm + (60 cm + 35 cm + 60 cm + 35 cm) * 28.57 cmSA = 9,628 cm^2The surface area is 9,628 cm^2.
