i know a triangular prism has 5 faces and six vertices if that helps
Answer:
56 inches
Step-by-step explanation:
4 feet in inches is 48
48+8=56
Answer:
A₁ = 950 mm²
Step-by-step explanation:
region 1 is a trapezium with area (A₁ ) calculated as
A₁ = h (b₁ + b₂)
where h is the perpendicular height between bases and b₁, b₂ the bases
here h = 38 , b₁ = 30 and b₂ = 20 , then
A₁ = × 38 × (30 + 20) = 19 × 50 = 950 mm²
1
Set up the long division.
648|9
2
Calculate 900 ÷ 648, which is 1 with a remainder of 252.
0.01648|9.6.482.52
3
Bring down 0, so that 2520 is large enough to be divided by 648.
0.01648|9.6.482.520
4
Calculate 2520 ÷ 648, which is 3 with a remainder of 576.
0.013648|9.6.482.5201.944576
5
Bring down 0, so that 5760 is large enough to be divided by 648.
0.013648|9.6.482.5201.9445760
6
Calculate 5760 ÷ 648, which is 8 with a remainder of 576.
0.0138648|9.6.482.5201.94457605184576
7
Therefore, 9 ÷ 648 ≈ 0.0138.
0.01380.0138
The formula to find the volume of a pyramid is: V=lwh/3 therefore:
V = lwh/3
38 = 6(6)(h)/3
114 = 36(h)
h = 3.17 (2 dec. places)
The height of the square pyramid is 3.17cm.
