2 answers:
Answer:
C) 700 unit².
Step-by-step explanation:
Given : A rectangular prism .
To find : What is the surface area of the rectangular prism below.
Solution : We have given that a rectangular prism with
Length = 14 units,
Width = 12 units
Height = 7 units.
Surface area of rectangular prism = .
Plugging the values
Surface area of rectangular prism = 2 ( 14* 12 + 7 *12 + 7 *14)
Surface area of rectangular prism = 2 ( 168 + 84 + 98)
Surface area of rectangular prism = 2 ( 350).
Surface area of rectangular prism = 700 unit².
Therefore, C) 700 unit².

Answer:
142.2 meters.
Step-by-step explanation:
We have been given that a box measures 70 cm X 36 cm X 12 cm is to be covered by a canvas.
Let us find total surface area of box using surface area formula of cuboid.
, where,
= Length of cuboid,
= Breadth of cuboid,
= Width of cuboid.
Therefore, the total surface area of box will be 7584 square cm.
To find the length of canvas that will cover 150 boxes, we will divide total surface area of 150 such boxes by width of canvass as total surface area of canvas will also be the same.
Let us convert the length of canvas into meters by dividing 14220 by 100 as 1 meter equals to 100 cm.
Therefore, 142.2 meters of canvas of width 80 cm required to cover 150 such boxes.
