Answer:

198 cm²

Step-by-step explanation:

We are given the dimensions of a rectangular prism;

3cm 9cm and 6cm

We are required to determine its surface area;

We need to know that;

Surface area of a rectangular prism is given by;

A = 2(WL+HL+WH)

Where L, W and H are length , width and height respectively;

Assuming;

Width is 3 cm

Length is 9 cm, and

Height is 6 cm

Then;

Area = 2 ( (3×9) + (6×9) + (3×6))

= 2(99)

= 198 cm²

Therefore, the area of the rectangular prism is 198 cm²

Answer: $6\dfrac{3}{8}\text{ inches}$

Step-by-step explanation:

Given: Original length = $15\dfrac{1}{8}$ inches

$=\dfrac{8\times15+1}{8}=\dfrac{121}{8}$ inches ( In improper fraction )

Length of piece cut from original = $8\dfrac{3}{4}$ inches

$=\dfrac{4\times8+3}{4}$ $= \dfrac{35}{4}$ inches ( In improper fraction )

Length of piece leftover piece = (Original length ) - (Length of piece cut )

$=\dfrac{121}{8}-\dfrac{35}{4}\\\\=\dfrac{121-2\times35}{8}\\\\=\dfrac{121-70}{8}\\\\=\dfrac{51}{8}\\\\=6\dfrac{3}{8}\text{ inches}$

Hence, the leftover piece will be $6\dfrac{3}{8}\text{ inches}$ long.

The volume of Cube A is 8 cubic inches. The face of Cube B has an area of 64 square inches. Which cube has a greater side lengt

defon

The cube which has a greater side length according to the task content is; Cube B.

<h3>Which cube has a greater side length?</h3>

It follows from the task content that since cube A has a volume of 8 in³, it follows that its side length is;

s(A) = ³√8 = 2in.

Also, since one face of cube B has an area of 64 in², it follows that the side length is;

s = ²√64

s(B) = 8 in.

Hence, Cube B has the greater side length.
