We need to find the surface area and volume for each rectangular prism. Here are the formulas I'm going to plug each prism's measurements.
S.Area=2(lw+wh+lh)
Volume: lwh
Question 75:
Volume: 3×1×3=9 cm³
Surface Area= 2(3)+2(3)+2(9)=6+6+18=30 cm²
Question 76:
Volume: 6×2×5=60 ft.³
Surface Area: 2(12)+2(10)+2(30)=24+20+60=104 ft²
Question 77:
Volume: 4×2×6=48 m³
Surface Area: 2(8)+2(12)+2(24)=16+24+48=88 m²
in simplist form it should be 3x+16
Answer:
60ft
Step-by-step explanation:
h x 20 = 120
h=120/20
h=60
Answer:
The sum of first five term of GP is 19607.
Step-by-step explanation:
We are given the following in the question:
A geometric progression with 7 as the first term and 7 as the common ration.
Sum of n terms in a geometric progression:
For sum of five terms, we put n= 5, a = 7, r = 7
The sum of first five term of GP is 19607.
Verification:
Thus, the sum is equal to product of 2801 and 7.
