First of all, Elena is kinda dumb why put brochures on only 80%? Nevertheless, 400 letters will not contain a brochure. If you need an explanation just comment that you need one on this.

A cuboid has a square base of side x cm. The volume of the cuboid is V cm^3 and the height is h cm.
Lemur [1.5K]
You will need the formula for finding the volume of a rectangular prism (cuboid).
V = l x w x h

1. V = x^2 x h

2. To solve for x, you will substitute in the information you know.

150 = x^2 x 24
Divide both sides by 24 to get

6.25= x^2
The square root of 6.25 is 2.5.

x = 2.5 cm

Please asap correct answer gets brainliest
weeeeeb [17]

Answer: 36 square units

Step-by-step explanation:

Divide the figure into 2 shapes: a rectangle and a triangle. Count the squares to find the dimensions of each figure. The rectangle has a width of 4 units and a length of 6 units. The triangle has a base of 6 units and a height of 4 units.

The formula for the area of a rectangle is length * width. The area of the rectangle is 4*6 = 24 square units.

The formula for the area of a triangle is (base * height)/2. The area of the triangle is (4*6)/2 = 24/2 = 12 square units.

Add the areas of both the rectangle and triangle. 24+12 = 36 square units.
