The surface area of a rectangular prism can be calculated using the formula:
Surface Area = 2lw + 2lh + 2wh
Plugging in the values:
Surface Area = 2(10)(9) + 2(10)(3) + 2(9)(3)
Surface Area = 180 + 60 + 54
Surface Area = 294
Therefore, the surface area of the rectangular prism is 294 square units.

What is the missing width of a rectangular prism with a length of 6 cm, a height of 4 cm, and a surface
area of 188 cm ?(1 point)
area of 188 cm ?(1 point)
To find the missing width of the rectangular prism, we need to use the surface area formula and plug in the given values:
Surface Area = 2lw + 2lh + 2wh
Plugging in the values and the known length, height, and total surface area:
188 = 2(w)(6) + 2(4)(6) + 2(w)(4)
188 = 12w + 48 + 8w
188 = 20w + 48
20w = 140
w = 7
Therefore, the missing width of the rectangular prism is 7 cm.
Surface Area = 2lw + 2lh + 2wh
Plugging in the values and the known length, height, and total surface area:
188 = 2(w)(6) + 2(4)(6) + 2(w)(4)
188 = 12w + 48 + 8w
188 = 20w + 48
20w = 140
w = 7
Therefore, the missing width of the rectangular prism is 7 cm.
