Find the volume and surface area of this prism.
mina [271]

Answer:

V = 408 cm cubed

SA = 558 cm squared

Step-by-step explanation:

To find the volume of a prism, multiply the area of the base by the height. This is 1/2 times width times height times length.

V =1/2 l*w*h =1/2* 6*8*17 = 408

To find the surface area of a prism, find the area of the triangular base and the area of each rectangular side.

Area of the base is A = 1/2 * b*h = 1/2 * 6 * 8 = 24. Since there are 2 bases, the area is 48.

Area of the rectangular side is A = b*h = 17*10 = 170. Since there are three, the area is 3*170 = 510.

The surface area of the prism is 48 + 510 = 558.

What is 9.01x10^3 in scientific notation
Alchen [17]
9.01 * 10^3 in scientific notation is 9.01 * 10^3.

I got this answer by moving the decimal so there is a non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent of the 10. If the decimal is binge move to the right, the exponent will be negative, but if the decimal is being moved to the left the exponent will be positive.

I hope this helps! :>
