Step-by-step explanation:
15y is less than 36+9
y is less than 45/15
y is less than 3
In order to find the shaded region the first thing you have to do is find the area of the two small triangles, then find the area of the big triangle. Subtract the area of the small triangles from the big one and that is the area.
Step one: 11×12=132
Step two: 132÷2= 66
Step three: 66+66=132 (because there is two small triangles with same dimensions)
Step four: 40×15=300
Step five: 300-132=168
Answer 168m^2
Using the values they give you:
Length= 5cm
Width= 3cm
Height= 8cm
and using the formula:
length x width x height = 5 x 3 x 8 = 120 cm^3
The volume of the box is 120cm^3
