Two dimensional nets and surface area - quiz - level
what is the total surface area of
three of these ice cubes?
aft2
30 ft?
24 ft?
18 ft2

Step-by-step explanation:

The complete question in the attached figure

we know that

The surface area of a cube is equal to the area of its 6 squares faces

so

The area of one square face is equal to

where

b is the length side of the square

we have

substitute

---> area of one square face

Find the surface area of three cubes

Multiply the area of one square face by 6 (one cube has 6 faces) and then multiply the result by 3 (3 cubes)

so

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
