Find the surface area of the pyramid
1 answer:
Answer:
2100
Step-by-step explanation:
Surface area is the area of all the sides
The area of the rectangular base is W x L = 30 x 30 = 900
Then to find the area of the triangles its bh
A = 30 x 20
A = 600
A = 300
Since there are 4 triangle faces on a pyramid we times 300 x 4 = 1200 is the area of all the triangles
Then we add the area's
1200 + 900 = 2100

Answer:
Volume of one cube shaped block is, 0.125 cubic feet
Step-by-step explanation:
Volume of a cube(V) is given by:
.....[1]
where a is the edge length of the cube.
As per the statement:
Cube-shaped blocks are packed into a cube-shaped storage container. The edge of the storage container is 2 1/2 feet.
⇒
It is also given that:
The edge length of each block is 1/5 the edge length of the storage container
⇒
Substitute this in [1] we have;
Therefore, volume, in cubic feet, of one cube-shaped block is, 0.125
