Answer:

googles explanation is below

Step-by-step explanation:

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.

Menjawab:

1.1 cm

Penjelasan langkah demi langkah:

Volume kubus, V = a³

Dimana a = panjang sisi kubus

Untuk V = 1.331 cm³

Panjang sisi 'a' adalah:

V = a³

1,331 = a³

Ambil akar pangkat tiga dari kedua sisi

(1,331) ⅓ = a

Two rectangular prisms have the same volume. The area of the base, B, of the blue prism is 418 square units. The area of the bas

kenny6666 [7]

Answer:

The height of the blue prism is half the height of the red prism

Step-by-step explanation:

Represent the volume of the blue prism with Vb and the red prism with Vr

So, we have:

$V_r = V_b$

$A_b = 418$ --- base area of the blue

$A_r = \frac{1}{2}A_b$ --- base area of the red

Required

Determine which statement about the heights of the prisms is true

Volume is calculated as:

$Volume = Base\ Area * Height$

For the blue prism:

$V_b = A_b * h_b$

For the red prism

$V_r = A_r * h_r$

Equate both volumes

$V_r = V_b$

$A_r * h_r = A_b * h_b$

Substitute the expression for $A_r$

$\frac{1}{2}A_b * h_r = A_b * h_b$

Divide both sides by $A_b$

$\frac{1}{2} h_r = h_b$

This implies that the height of the blue prism is half the height of the red prism
