Answer:
Option C is the correct answer.
Step-by-step explanation:
Volume of box = Length x width x height.
Volume of box = 36 cubic centimetres.
Option A:
Length = 12 cm
Width = 12 cm
Height = 12 cm
Volume = 12 x 12 x 12 = 1728 cubic centimetres.
Option A is wrong.
Option B:
Length = 4 cm
Width = 4 cm
Height = 2 cm
Volume = 4 x 4 x 2 = 32 cubic centimetres.
Option B is wrong.
Option C:
Length = 3 cm
Height = 3 cm
Volume = 3 x 4 x 3 = 36 cubic centimetres.
Option C is correct.
Find the area of each shape (rectangle and triangle) and then add the areas together.
Area of rectangle:
A = bh
A = 14*12 = 168 cm2
Area of triangle:
A = 1/2*bh
A = 1/2(16)(21 - 12)
A = 1/2(16)(9)
A = 1/2(144)
A = 72 cm2
Add areas together: (area of the whole shape)
168 + 72 = 240 cm2
58.5
0.65 decimal form
then times that by 90
then you got the answer 58.5
