Answer:
Step-by-step explanation:
So the area of a cube is a²
This means that:
2² = 4cm²
So the area of a triangle is (b*h)/2
This means that:
(3*2)/2 =
6/2 = 3cm²
4cm² + 3cm² = 7cm²
Overall area is 7cm².
I don't know if it's 74, but I got -80. here's how:
(3x + 5 x -4x + 7) (-4)
(8 x -4x + 7) (-4)
(8 x 3) (-4)
24 x -4 = -80

The density of the wooden block is 0.50625g/cm^3
<h3>Density of a wood</h3>
Density is defined as the ratio of the mass to volume of a substance. The formula for calculating the density of an object is expressed as:
Density = Mass/volume
Given the following parameters
Mass = 32.4grams
Volume = 4^3 = 64 cubic centimeters
Substitute
Density = 32.4/64
Density = 0.50625g/cm^3
Hence the density of the wooden block is 0.50625g/cm^3
