Please helppp? need to find volume:

15 yd³

Step-by-step explanation:

Formula for the volume of a square pyramid is V = 1/3 Bh

So...

V = 1/3 (3*3)(5)

V = 1/3 (9)(5)

V = 1/3 (45)

V = 15

Simplest form of radical √245c³ = 7c√5c

Step-by-step explanation:

Given radical value:

√245c³

Find:

Simplest form of radical √245c³

Computation:

Given value

√245c³

Step 1 :

Prime factorisation of given radical value

Simplest form of radical √245c³ = √5 × 7 × 7 × c × c × c

By taking 7 and c from out of root

Simplest form of radical √245c³ = 7 × c √ 5 × c

Simplest form of radical √245c³ = 7c√5c
