I’m pretty sure the answer is b=1
Answer:
A. (10x4x5) + (5x5x5) Cubic Inches
Step-by-step explanation:
Unit must be cubic inches because you are discussing volume.
Calculate volume of bottom rectangular prism first, then the volume of the upper cube.
The area of the square is 25=5x5
The height of the triangle is 4 and the length of the bottom is 5. Therefore, the area of the triangle is (1/2)x4x5= 10
The answer is 25+10=35

Answer:
10.92
Step-by-step explanation:
1. Find all side lengths of this tetrahedron.
A to B is 2 units
A to C is 2 units
A to D is 2 units
B to C is square root of 8
B to D is square root of 8
C to D is square root of 8
See 3D distance formula attached below to get the answers above.
2. Find the area of the triangles
Triangle ACD can be calculated using Heron’s formula, which is also attached below.
Area of Triangle ACD is 2 units squared.
Area of Triangle ABD is congruent to the previous one so it is also 2 units squared.
Area of Triangle CBD is roughly 3.46 units squared.
Area of Triangle ABC is congruent to Triangle CBD so it is also 3.46 units squared.
Adding them altogether is 2 + 2 + 3.46 + 3.46 = 10.92
