Answer:
The surface area of Rectangular prism is .
Step-by-step explanation:
Given:
Length of the rectangular prism = 7 cm
Width of the rectangular prism = 5 cm
Height of the rectangular prism = 12 cm
we need to find the surface area of rectangular prism.
Solution:
the surface area of rectangular prism is equal to 2 times sum of length times width and width times height and length times height.
framing in equation form we get;
the surface area of rectangular prism =
the surface area of rectangular prism =
Hence The surface area of Rectangular prism is .
Answer:
376
Step-by-step explanation:
2(8x10)=2(80)=160
2(10x6)==2(60)=120
2(6x8)=2(48)=96
160+120+96=376
Answer:
9.6 cm
Step-by-step explanation:
Since the scale factor is 3 (you can figure that out by dividing the larger side of the triangle by the one on the smaller triangle that is the same side) you would divide all other sides by 3 to find individual lengths.
9.6/3 = 3.2
7.2/3 = 2.4
We already know the other side, 4.
3.2 + 2.4 + 4 = 9.6cm
Answer: x < 3
Step-by-step explanation:
Let's solve your inequality step-by-step.
7x−9<12
Step 1: Add 9 to both sides.
7x−9+9<12+9 =7x<21
Step 2: Divide both sides by 7.
7x/7 < 21/7
Answer: x < 3
The equation is base area x height so is 11/4 x 4 x 3 1/4 = 35.75
