What is the surface area of the rectangular prism?
(1 point)
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)
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.
