What is the volume of a cube whose surface area is 294

V = 343unit³

Step-by-step explanation:

This is a solid shape problems a three dimensional.

Surface area of a cube = 6s² and the Volume = s³.

Since the surface area is given to be 294, we now use this to calculate the s.

Now,

6s² = 294, now solve for s

s² = 294/6

= 49

s² = 49

Now, to find s, we recalled the laws of indices by taking the square root of both sides

√s² = +/- √49

s. = +/-7unit.

Now to find the volume of the cube, where

V = s³ and s = 7, therefore

V = 7³

= 343unit³

correct

step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
